the apps have been in the stores for years. What is the reason why you believe that something happens soon?
Unpopular opinion: Because of this problem, because of the refusal of relays block image links which contain CSAM, several of the major Nostr apps, possibly including nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q , nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg , and nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 will be kicked off the Play Store and App Store. This might happen fairly soon, too. Web applications will be fine and won't be impacted. Relying on "user reports" or "web of trust" is a joke and won't prevent these apps from getting killed by Apple or Google. Sorry.
Discussion
Fair point. I guess, I'm fairly new to Nostr, just a few months, and I've seen some pretty horrible things, and then I post about it, and it turns out a lot of OTHER people have seen some pretty horrible things, and recently. So at least I know that:
1) There is a problem
2) The problem is unsolved
It's true I don't know much more than this.
