Personal experience, but I have not found a single person who likes MS Teams. Usually people around me say that Slack is ok-ish, while MS Teams is crap.
I've the misfortune of being forced to use Skype and I would kill to have it replaced with Teams at my workplace.
There is a half-baked link between Skype and Lync to make it seem like it's the same product. This link is all shitty mainly because Lync and Skype work completely differently, and even simple things like call signaling have to deal with years of legacy Microsoft SIP extensions that were punched into Lync.
I remember the first time we received access to the Lync code repository. That stuff was a multi-GB (!!!) repository that contained files, promo videos, PDFs, code, etc. That tells you much about the development practices behind Lync.
It's not great, but in the corporate space, Teams does an OK job, and MS is a reputable company for B2B.
Corporate standard at my place of work. I hate Hangouts with a passion. It's the worst messenger, feature- and UI- wise that I've seen for years.

No it isn't. Used Teams at another company which adopted it as the standard. Couple of years ago. Feature-wise it was like a proof of concept, very early access.

Again, I worked at another company where Skype for Business was the standard and nobody ever used it unless they needed formal IT help or something.
All the teams I'm acquainted with at my current place refuse to communicate on Hangouts and, in violation of corporate policies use something else like Slack or Mattermost.
Seriously, go use products like Google Hangouts, Slack or Microsoft Teams (Microsofts's surprisingly better clone of Slack) and then tell me that Skype was ruined by integrating with Microsoft's other product base. The closest argument you might be able to make is that Skype could have developed new features or updated its UI and stayed competitive, but that wouldn't give them the competitive edge that it's competitors nearly all had in terms of being backed by major tech companies. Additionally, the major revenue source was Business tier use, which Microsoft dramatically improved by integrating it with their other cloud-based business suite applications.
Microsoft didn't kill Skype, if anything they extended its life expectancy and value in markets that actually paid to use it. It's dead/dying now because better tools have been developed and marketed to replace it. That's just standard product life cycle.
