I can't say I went all the way but I think I'm past the middle.

I try as much as possible to own the tools I use through self-hosting (mail, mastodon, pixelfed, matrix, lemmy, blog, cloud, firefox sync, photo hosting, rss, ...) and when it's not possible I choose privacy-oriented ones but sometimes floss alternatives just aren't good enough and I won't/can't sacrifice the required efficiency.

That's the case for search engines, I use my own searx instance but sometimes I just can't find what I'm looking for so I switch to google for those.

My biggest issue is that I could not find an alternative that suits me to Youtube, I like peertube but there isn't enough content for me and I don't have the resources to host it (to control the federation settings).

As for android, I used to bother with aosp projects in the past but I don't have the time anymore so I just rooted my device and disabled as much junk as I could and use f-droid as much as possible.
