Sounds like a good project, I also hate that Instagram pushes algorithm-driven content into your face everywhere without any options to turn it off, it's good to fight against these toxic dark design patterns.
Can also recommend using Instagram with the IGPlus web extension. Or for a native Android version there's also DFinstagram.
For YouTube there are many web extensions as well. On Android the YouTube ReVanced patch is really good though.
Well, you don't even have to fight these patterns or these apps
Just stop using these stupid apps overall. 95% of the content you find on them is useless. And today, a staggering amount of content is also fake AI crap. Save your sanity and time and remove these apps.
Yes, I think it's good to uninstall these apps from time to time as well.
Deleting and never using them again doesn't work for everyone though. For me it's useful to stay in contact with people, I also use them to promote work as well as find cool events.
Android has good patches for everything except X thanks to Elon's meddling. There's a cumbersome workaround but I'm just choosing to use it within brave, or other PWAs offerings.
