Yet... I still use Android-based devices. They happen to be Google-free, i.e. no Google Services nor any Google apps, no Chrome or Chromium, no Google search engine. Instead of those Google apps I use things like ~Osmand (maps), Nextcloud (storage and some applications), etc. Firefox/Fennec and Privacy Browser for web-related things. A self-hosted Searx instance for searching. Peertube for video, Airsonic for audio, Libreoffice Online (integrated into Nextcloud) for that type of stuff, eJabberd for chat, now experimenting with Pixelfed for photo sharing, self-hosted mail/web/etc. I've been doing something like this for as long as I've been using Android, i.e. about 9 years.
Though I have no idea why would anyone trying to hide from Google. You can't really. Google spies on you everywhere, from every website. They already have all data and you can't do anything about it. It won't be much worse if they'll have a bit more data.
I have to disagree here - Google explicitly monetizes their information on your activity on the Internet, Apple does not.
