> Native apps on native platforms have intense access to systems. They don't have the secure sandbox of the web to protect them.

So you complain mostly about iOS and Google's Android, and at the same time you say that native apps are not sandboxed? You can't just cherry-pick whatever you want, right? Apps are very much sandboxed on iOS and Android.

The fact is that there are TONS of alternatives. You just focus on the web because you can't be arsed to look at them.

Not happy about iOS, Google Android or Windows? Then how about you look at AOSP-based systems like GrapheneOS? No need to use the Play Store there, AT ALL. How about you distribute your app on open OSes like Linux and *BSD? Even better: you mention open source a lot. Then no need to distribute, just open source your code. If it's interesting enough, someone on the actually open platforms will pick it up.

And instead of teaching developers how they should develop for Google Chrome, try teaching people how they could actually use something that for them will be indistinguishable from Android: like GrapheneOS.
