You can disagree with whatever you want, that's your opinion, this doesn't mean I shouldn't be able to do just because you have that opinion. But to make this clear, that's not what I'm trying to implement, this is already implemented by itch.io, so they already have what you so called "aggressive" marketing strategy built-in and already being used, if you disagree with that, there is an option on your profile to turn this off, and if I remember correctly, will turn off the emails from that feature I pointed as well, simple like that, actually I think you can even turn Itch emails on and updates from games off...
See, I think you are just putting your bias without actually thinking, just to be that "ohh I praise so much my internet privacy" standard. What I mean by that is: this tool that I pointed is a tool from Itch they are in power of deciding what this tool does or not, for instance, we can't send more than 1 email/week per project, they can turn this down to 1/mo for free downloads if they want. This is all already controlled by Itch, which you claim to trust, and thus this is not a "direct line to your private email", Itch is under all the control of this tool, if I send something using this tool I am almost sure they have access to that content, so if you trust Itch, you are already trusting what I'm proposing here, this is already available, this is already being used, I guess that never annoyed you, so why bother now? At the very worse scenario you can have a "player email" that you never look at, and tell itchio to use this email for updates 🤷🏻
I mean, all I want is to include free download to that feature.
