I think thats a very bold statement about what the public lost interest in or how much satisfaction there is with thin clients. I worked managing thin clients before and everyone hated them pretty much universally. The only people that liked it were the bosses because they said it saved money (but there was serious friction because of constant complaints)
Worst job I ever had because I had zero power to help people because of how locked down the systems were. If it was a for-profit business, they would have gotten axed, but it was taxpayer dollars at work so complaints fall on deaf ears, mostly. The only thing I kept thinking is that someone must have really thought they can make one of my skill sets useless, and that they have failed.
That is what I think, there is adoption by organizations that basically have no performance metrics (horrible accountability) and change incredibly slowly, that makes it seem like they are popular. I also saw a med doctor go haywire when his thin client bullshit system was acting up. Of course its a 'jump' type organization, where everyone wants to GTFO, there are zero 'lifers' and its only tolerated because the attrition is so damn high for multiple reasons. By jump I mean like a resume filler/looking for another job thing, where its just like a crappy springboard. Those places are like 'damned'. They also like to have zero-tolerance rules, it just seems to go with the territory, so they can prevent experience based pay increase from occurring.
Oh yeah its also not doing its job of being secure (main selling point, that it was supposed to be so secure that there would
never be a problem), given how I get regular mail about 'data-break-ins' that invite me for class action fun.

It has the obvious marketing of being a 'golden bullet' solution that will eliminate computer problems, get rid of IT and allow you to be 'cutting edge' with no work. Yeah, golden bullets don't work. I suggest keeping "too go to be true" in mind when you listen to the spiel, your skepticism will save your butt. Does the rhetoric advocating for these changes not sound exactly like "
there has been a paradigm shift in the computing industry"? (wow, no one has been making fun of paradigm shift related corpospeak marketing recently... maybe that is why so many companies are getting owned after blindly rushing into a AI focus, what is it, too 2000's to ever happen again, they can't bear to miss out on the profitable paradigm shift?)
If I had to make a list of how to scuttle an organization while making your own career, I would say adopting thin clients is a real good bullet point.
