I find it increasingly difficult to believe that Itch.io is seeking a new payment processor. I think they made that claim simply to shut us up. And I don't see any point trying to juggle my work across Itch.io and Subscribestar when Itch.io is so hostile to my work.
If Itch.io eventually does comes through and fix their platform, I'll consider putting more of my games on the site. Until then, Itch is not worth my time and effort.
Yeah, itch.io said at some point something about "oh we're looking for a new payment provider" but I think they're just quietly hoping that we all forget about it. I still plan to participate in some game jams here but if I ever release anything else substantial, I'm likely to just register a dot com, make a page for the game here with just screenshots and a link to my main site once it's up and running.
