Github gained actions, sponsors etc. and keeps getting more new features. Whatsapp got E2E chats and group video calls and handles communications for a huge amount of people.

I think Github has held up pretty well.

Why should they? Acquisition today means: you have managed to become a threat to us, so we buy you so that this threat disappears.

I just hope Adobe doesn't buy Affinity.

Does YouTube count? I know it's had it's controversy but it's still miles better than if it hadn't been acquired.

Powerpoint, Google Earth and Android are three that I use all the time and instantly spring to mind.

edit: Hotmail can arguably be on that list. Revit should probably also qualify

Github. Apple buying Workflow to build it into the OS as Shortcuts.

MS's acquisition of Github seems to be going okay, and has arguably increased user value. It's hard to say what MS is getting out of the deal, though; the mistrust of MS runs deeply given its history, so the biggest strikes in this deal are speculation about what MS is doing with the massive trove of Github developer and code-over-time data. IMHO the longer MS owns Github without hurting or exploiting its users, they are restoring lost trust with devs, but there are lots of devs who can/will never really trust MS or anything it touches (which TBH is a pretty safe bet).

Minecraft. Ring doorbells.
