A lot of things but a big part of it was ads and features. Skype eventually built in its own instance of Microsoft Edge specifically for displaying ads constantly and at the same time kept adding features no one wanted or asked for. The audio quality of Skype had also hit a platform where they weren't willing to make it better than it needed to be to compete with Ventrillo or Teamspeak. When covid happened and all the loonies cut off real life interaction, Zoom and Google Meet were in competition with skype and both had more desirable features, both were more accessible to the dumbest of normies without app installations, and Skype's server bandwidth for group calls was fucking ATROCIOUS. Not to mention Discord was coming out with its EXCELLENT audio quality, better group netcode, and persistent group servers for free.

So yeah Microsoft aquired Skype and tried to make it a classic Windows Bloatware app with retarded features and premium services no one wanted while several competitors were just better to use for whatever demographic your group fits into.
