Article 13 will not kill itch.io. I'm not sure what "I heard it will" means, is there some source saying that it will?
From what I understand, itch.io classifies as a "small enterprise" and is not subject to the regulations being announced . The regulations are effectively designed to attack large internet companies. These laws do set a dangerous precedent though, since if they were expanded then it would enable the larger platforms to continue operating with their capital and block out smaller platforms from ever starting
If we grow past the threshold then we will investigate adding automated content filtering services. Something like this will most likely come from a third party service that is in compliance, since burden it would place on us to run ourselves would be great.
Disclaimer: we're still going over it to fully understand how it will affect us in the future. We have no intention of blocking EU users from accessing itch.io. We may change our plan of action as we learn more things.
