I think it's due to how they cultivated the image of their walled garden app stores as curated and moderated against "bad stuff" like adware etc and now you have people with a puritan/sex-regressive stance leaning on that image and sesta / fosta bills to "protect us all".

With the recent push for PWAs, it will be interesting to see if communities like artstation use these instead.

I am wondering why are not just tagging this apps, then by default not allow you to install unless you confirm on an alert box and put your password. Seems a win-win, you keep both camps happy and probably spend less on attempting to filter your content so not to trip over AIs detection algorithms and bad moderation from the stores.

It's not an outright ban, but it's not far off: https://safebrowsing.google.com/

They could add editorial policies to those criteria whenever they wanted. Or change a line of code to turn a drastic warning into a full block.

It should be illegal to do that.

I assume it's due to firefox, i.e./edge, opera, and so on.
