sure, app stores are the next problem (and we're already seeing a lot of this with all the nostr zaps issue), but thats a harder problem to solve atm.

with custodial entities they need to make a reasonable effort to cut you off. Its not just about removing it from the app store, they will end up doing things like firewalling off country ip spaces etc, so even if you get the apk you need to vpn to an "approved" geography to use the service

and you have to think of the second order consequences - if the self custodial wallets have the user numbers of WoS then it will be easier for them to get more funding -> more research and development -> better ux for users, possible alternatives to app store etc.

the problem is also the mentality of the users, you can see the same responses every time - people demanding that companies and founders fall on their swords,screaming outrage and rugpull every time something like this happens, even tho its inevitable given the current legal and regulatory env globally.

Its impressive WoS operated globally for as long as they did( with them being shut down/changing how they operate at some point a certainty).
