Summary: Apple, Amazon, Google getting worse; Microsoft getting better; Facebook is Satan. That chimes with my experience of the changes over the past few years....
It can only be wrong, as Microsoft Teams plays nowadays a big role in many people’s life’s. ;)
I'm in the UK education sector which seems to have become a Microsoft shop. Teams seems fine to me, but I think it's only because they nicked the idea from Slack. Outlook is... better than it was, but still no match for Gmail. OneDrive is incomprehensible. All the Office 365 stuff just seems like a big overcomplicated mess.
