I agree that it’s not surprising, but I’d suspect that the name and a lot of the infrastructure will remain in various places. As others in the thread have pointed out, Teams appears to use a lot of Skype’s architecture.
GroupMe is also still listed on the App Store with Skype as the developer, though their website lists Microsoft as the developer instead. GroupMe has seen recent feature updates, so I’d suspect it would be mostly unaffected. Interestingly enough, GroupMe still has a public API [1], so in that sense it is more open than Skype is these days.
Also of note is that the Microsoft Account sign-in screen still accepts legacy Skype names as an alternative for an email address or phone number. It would be interesting if the ability to log into Microsoft Accounts this way outlives Skype itself.
My day-to-day computers have always been Macs. My use of Windows has been relegated to occasional specific devices, like a TabletPC sketchbook or a 3D workstation. I don't think I'd touched Windows in more than a dozen years when I got a gaming handheld last year.
It asked me for a Microsoft account (which I presumed I didn't have) or Skype. I took a guess at my old Skype credentials and proceeded with setup. I was both surprised and upset to discover that by username on the device was a 5 character truncation of my old Skype handle.
My user profile directory on my PC is `c:\users\efrea`, which is exceedingly annoying given my muscle memory typing out my username. I "fixed" this with a couple junction points (both `efreak` as used on my Linux systems, and my first name as was used on my previous Windows systems), because I frequently use RDP from my android tablet and autocorrect keeps changing it to my full username. This is the second annoyance after finding out early on that changing my username doesn't mean changing my profile directory name (at this point there's too much software and scripts with hard-coded paths, both locally and remote, to change it without leaving the junction).
I would vastly prefer my username to be my usual username, with the display name being my real full name, but my Microsoft account apparently doesn't allow this (likely due to my privacy settings).
