Then:
* Removal of peer to peer
* Windows UI redesign, away from classic usable Windows
* Mac UI also changed to web-style (which (obviously personal opinion) was a real kick in the face to people who use Macs and valued Mac UI. The UI wasn't flashy. It worked and it fit the system.)
* Emojis everywhere. I used to use it for work. I recall an eternally bouncing emoji for a while during every work call. Incredibly distracting.
* Covid's opportunity completely missed. Zoom and the rest took over.
* Oh, no-one's using Skype, I wonder why.
If they brought back Skype as a well designed, native UI-first, peer to peer, secure, EU-governed platform it stands a chance of outstanding success.
„By the creators of Skype“ would of course also carry significant weight.
