The worst decision Google ever made?
I'm told it has resurfaced as something called Google Meet.
Microsoft's equivalent (of losing to Zoom, not their worst decision) would be buying Skype for $8.5 billion when it wasn't worth that much, changing features that made the beloved brand unusable for years, then rebranding it as Teams and forcing me to see that never-used logo in the bottom right corner of Windows. Never used it, never will, want it gone, but I can't. On the upside, I've heard that Teams is usable, and a worthy competitor to Zoom.
What's your candidate?
