Erm, while I agree Skype wasn't the pinnacle of chat software pre-MS acquisition, I believe OP is referring to their absolute butchering of the consumer client[0].
Anecdotally, I stopped using Skype for iOS shortly after it was changed because it went from a solid, reliable internet-calling service to probably the most buggy / laggy interface I could have expected.

You're totally off your rocker. They undeniably obliterated Skype in every possible way. Literally, it is an absolute abortion. Look on ANY community site about Skype, you will see its 95% livid rage to this sorry excuse of an app (including me, I actually used Skype for everything, now I'm forced to use the old version which hopefully isn't deprecated). https://www.reddit.com/r/skype/search?q=new+skype&restrict_s...
> Skype was pure garbage before MS acquired it.
You have a weird memory. Skype was a very nice thing back in ~2009-2010.
Skype grabs port 80 and 443 by default, which is not very nice. Since at least 2010, but ISTR even earlier than that.
Started the browser wars? Too bad the browser wars have been too small, because we obviously haven't learned anything from them.
