I agree. But to be very honest, de-googling is very important but not always very easy. So I did personally move away already from Gmail. I also now host my own Nextcloud instance, which I use for my agenda as well as contacts. Meaning I also don't sync or store contacts or anything in Google. I don't use any cloud services for storage either, again Nextcloud (self hosted) solved that for me.

Then I was never using ChromeOS, so that helps, I'm only using Linux. However, I do have an Android device. It's really hard to get rid of that, maybe a custom ROM, is that valid? Anyhow, and last but not least Google search, Google images, Google maps, etc. I don't want to go from Google Search to another big Microsoft corp, so moving to Bing is a no go. That also means all those meta search engines is also not a good alternative, which includes: DuckDuckGo, ecosia and alike.. Qitchain, presearch or Yacy isn't working for me either. It's just not good enough.

Thus finding a good search alternative is hard! I'm actually considering as a software engineer to build my own.
