I don't even bother installing apps anymore, I don't have time to research whether or not they are going to abuse my privacy or have some horrendous TOS. I got my core 10 apps and haven't bought a new one in a year.
I figure most things don't need an app unless they are trying to take more data anyway. Anything telling me to install an app whose mobile experience is fine already is very fishy to me. I'm looking at you, Reddit.
Facebook is my #1 example of this.
The app bloated up like it's primary purpose was to take up space on your phone. So I removed it and used the mobile website.
At first you had to refresh the page to get new messages. No big deal, but a bit annoying.
Then they updated and didn't even need to refresh the page to get an update to the thread you were in.
Then a few years back they decided you can't get messages in the mobile website, you must use their app. Later I learned about mbasic.facebook.com and have to switch to that when friends message me.
