Saw this a bit ago and somehow didn't connect it with StudioWhy. Neat to see you guys attempt a project like this. That said, you've asked for comments/feedback, so I'll give mine. Understand I don't mean to be overly cruel here, I'm just cynical/realist by nature.
I don't see this as being especially helpful.
There are four main problems adult creators face now: Legal persecution, hosting, discoverability, and payment processing. Of these four, WhyCloud only really helps with hosting, which is by far the least of the problems. Hosting is complicated and a bit of a hassle, but doable, if you have some basic tech knowledge. The other three are far larger problems, to the extent that hosting isn't really worth bothering with until they're dealt with.
1. Legal persecution: Over half of US states now have "porn ID" laws, with more on the way, which effectively outlaw explicit content, including drawn content, on a practical level, as only the largest sites will be able to afford to implement verification systems, and most people will be unwilling to give their ID to random shady 3rd party services that totally aren't storing them up for blackmail or laziness until they get hacked and leaked.
If you run a website with explicit content and someone in these states manages to access it, enjoy paying $10k per day in fines. This has already been found to be acceptable by the Supreme Court (Free Speech Coalition v. Paxton) and lawsuits are already being filed.
2. Discoverability: With the exception of a few titles that got nuked from orbit on Itch during the recent funtimes, all the games that were here previously are still here. Hosting is still, for the moment, available. But no new customers are discovering paid titles anymore, because they're all indefinitely (probably permanently) removed from search and recommendations. Setting up your own site is great and all, until you realize you're screaming into the void. No one will find you. No one will be buying something similar and see you in the sidebar and check you out. This is why we moved on from the 90s model of a bunch of isolated websites: discoverability was HORRIBLE. Technically it's not that hard to buy some hosting and slap some mp4s up somewhere, but everyone uses Youtube instead because if they don't NO ONE WILL EVER FIND THEM.
You've made some vague mentions of "federation" and teased some screenshots of a storefront-like page with search, but this seems like an "eventually maybe" feature rather than a core component, and historically federated systems have seen very poor adoption rates because most people, frankly, can't handle the complexity. People go one website, people click, do search, find games. People no understand wtf federation is or how it works. We got to see this play out in realtime as everyone fled Twitter not long ago, tried to understand Mastodon, and all their heads exploded with the effort. Discoverability is ESSENTIAL. Self-hosting, alone, is not a solution, and Federation is not a solution.
3. Payment processing: None of this matters if people can't get paid. And online, everything is MC and Visa. Paypal is MC and Visa. Square is MC and Visa. Stripe is MC and Visa. Patreon is MC and Visa. You get the idea. There are no alternatives in the US, and it's unlikely there ever will be. No one's going to use crypto, it's been regulated and bad-pr'd to death. "Adult" processors are useless: they're just for chargebacks from clueless boomers, they still have all the same censorship restrictions, and even THEY are now getting sued (Segpay just got pulled into the suit against Nutaku).
3 is essentially unsolvable, and may end up being the death knell for all of this. But if you want to attack the rest in the meantime, there's a much simpler solution than what you're proposing: e621, but for porn games.
Start with a booru engine and mod it. Every entry is a game, instead of a pic. Mod it so you can have multiple screen shots for each entry. Description text is the info for the game, source is links to it, wherever it's hosted. The booru is one site, run by one group of people, with entries and tags crowdsourced, everything easily searchable in one place. Easily usable by a caveman. No "federation", nothing to understand, it's just a site. Whole thing can adapt to "damage" in realtime, source links can be updated as needed, and point to any and all hosting and services that exist.
If you have people that understand the systems and programming involved, this should be doable in a few weeks, a month at most, with very minimal expense. I briefly considered doing it myself, but I don't have even the limited resources needed to attack a project like this, and am unwilling to expose myself to the legal risk of hosting ANY explicit content in the current environment, even just thumbnails and screenshots. But if you are, you're welcome to it.
Just an idea though. I just don't see the proposed framework for WhyCloud as really solving a problem that needs to be solved for most people. Having recently experimented with what's out there, it's not THAT hard to sign up with a cheap host, get a domain name and slap up some html. If people are capable of making complex games in the first place, they're probably capable of that. The problem is that if creators do that, they'll be tiny, isolated points of light in a vast abyss, with zero searchability, tags, recommendations etc. As much as I hate centralized platforms, we left the 90s Internet for a reason: Unless you got your website featured on a big blog or PRINTED IN A MAGAZINE (remember those?) no one would ever find you.
Again though, not meant as an attack on you, I'm glad you're trying to do something. I just don't see this, as described, as having a lot of utility currently. And paradoxically, if people are tech-illiterate enough that they can't handle hosting and basic wordpress config on their own, they probably won't be able to handle your "simple" system either.
