LibreOffice has been working "fine" for my DeGoogled personal life.
Work is heavily Googled still (and not entirely up to me), but I've practiced a hard barrier between work tech and personal tech for years now. In case I can sway any colleagues: Anybody feeling like any of these alternatives would be ready for a small or larger team to jump over to that routinely collaborates on spreadsheets, documents and slides?
Joined PeerTube last month and have had great success with it in terms of as a platform and place to share art / content, though of course the views have been low.
I'm sure there is a megathread elsewhere but would love to see an acceleration of folks adopting the Fediverse. My talking point has been to sort of sell Fediverse alternatives (Lemmy, Pixelfed, Mastodon) as superior to other big tech alternatives out there (such as BlueSky and Flashes). We are either at the vanguard of a mass migration or just migrating while no one else is intending to, which I guess amounts to the same thing!
The PurchaseWithPurpose community here on Lemmy and other platforms does a great job of pointing at achievable change by dissecting nine differences between available alternatives.
Privacy is a spectrum; I agree with comments here saying to look at these much more hardened principles still even if you won't ultimately be taking them up on all their suggestions
