As long as the illusion that AWS/clouds are the only way to do things continues, their investment will keep being valuable and they will keep getting paid for (over?)engineering solutions based on such technologies.
The second that illusion breaks down, they become no better than any typical Linux sysadmin, or teenager ricing their Archlinux setup in their homelab.
I would say tech workers rather than "people" as they are the ones needing to interact with it the most
Aside from Teams and Outlook Web, I really don't interact with Microsoft at all, haven't done since the days of XP. I'm sure there is integration on our corporate backends with things like active directory, but personally I don't have to deal with that.
Teams is fine for person-person instant messaging and video calls. I find it terrible for most other functions, but fortunately I don't have to use it for anything other than instant messaging and video calls. The linux version of teams still works.
I still hold out a healthy suspicion of them from their behaviour when I started in the industry. I find it amusing the Microsoft fanboys of the 2000s with their "only needs to work in IE6" and "Silverlight is the future" are still having to maintain obsolete machines to access their obsolete systems.
Meanwhile the stuff I wrote to be platform-agnostic 20 years ago is still in daily use, still delivering business benefit, with the only update being a change from "<object" to "<video" on one internal system when flash retired.
The truth is one under the age of 35 is able to configure a webserver any more, apparently. Especially now that static site generators are in vogue and you don't even need to worry about php-fpm.
