Skype wasn't originally written by Microsoft, so who knows how the code looks like. I know the linux client was god awful.

BTW, the old linux client (dating back to 2014) still exists and can be downloaded from the official site. It only supports text messages and files, and the messages don't show up in other clients for some reason as if they are not stored in the server side log. Can't explain that one.

Skype was developed by an outsourced team in Estonia.
