Also, my Skype credit simply disappeared from the account (granted, it had been sitting idle for a few years, but still).
WhatsApp, Signal and similar apps completely replaced Skype, which stopped innovating years ago. Other than some "automatic captioning" based on Bing, and interface changes that are annoying for computer-illiterate people, barely anything changed.
For several years, Skype had been a very lightweight way to communicate with people with not-so-good computers and flaky Internet connection. Trying to replace it with Jitsi, for instance, quickly shows how much more CPU is needed to run that instead. But then the Linux version started being packaged differently (Electron?), so that was lost as well.
Well, it will likely survive for some time on old companies that still use Skype for Business.
