Have you tried PhotoGIMP ?

Google Chrome? Privacy?

They can, if they modify activitypub for their own server

I think the keyboard issue is often overlooked and would like to know what recommendations your have? Or what should be known more?

Overlooked? Not really, for years I have never used built-in keyboard from stock rom, keyboards from goolag store or goolag board.

Most people stick with non-foss keyboards just because it’s convenient

Yeah, on their cloud. LoL

Using Google Chrome is already a bad idea. Google usually listens to your conversations from your phone through gapps.

I use xiaomi phone, unlocked bootloader, custom ROM with microG installed. As for system-wide adblocker I use combo dnscrypt-proxy+personalDNSfilter

None, I only use anti DPI and dnscrypt-proxy since our govt told ISPs to sniff internet connection using DPI

For desktop I use Ungoogled Chromium portable as a secondary browser, and DDG browser on Android
