17yo here, I know that I might be a bit of an exception here but atleast within my privacy conscious friend circle, I feel like they prefer websites more than apps and I feel like that plays an impact, (Obviously this might make a difference as well that for some of my generation, they only use phone so phone applications feel more intuitive to them)
I used to say to my elder brother that I wish to make websites not apps if I do because websites are more portable etc., but he said that websites are hard to monetize etc. rather than apps which are easier to monetize. I think that one of the reasons is also that app are easily monetized and this has become a norm to many people outside of HN/privacy-conscious sphere in general.
I really wanted to make f-droid applications sometime ago but I don't know Java and I really love how easy it is to make an applicaation in golang/python/any lang in desktops usually but I tried making an tauri android rust application from my desktop Linux and it was really frustrating, I feel like there are some very low hanging fruits privacy win where open source tools can be converted into just bare minimum-ly good UI/UX android/ios apps (which works) and be published to something like f-droid.
