Most software, but definitely not all. Steam, Resolve being the two biggest non-foss items on my desktop, while my ex-Chromebook has a proprietary screenwriting program, as well as OnlyOffice instead of LibreOffice because I need much better Excel compatibility for work and LO still isn’t quite there for it.
Phone android. But not entirely de-googled. Replaced drive with syncthing, keep with Joplin, photos, phone, and messenger with their Fossify equivalents and disabled the originals. Replaced gboard with heliboard, etc…
But can’t/won’t completely replace the OS yet because both google pay and android auto are essential to me and getting them working on most replacements is still a royal pain in the butt.
