Some of it is because how people interact with and use tech has changed.
Mobile users have completely outpaced laptop/desktop users, and mobile users don't think in terms of files and text, so to them copy & paste is less important. The mythical "average user" moves arbitrary text and data around using screenshots and screen recordings instead of text and files.
Yes, it's incredibly inefficient, but I think it's evolved that day because selecting text is a real pain on a small touch screen, and companies have been trying to abstract away any concept of a filesystem for a long time.
So you or I might care and be bothered that we can't copy & paste something from UI chrome or content in a "web app" but the average person won't care, they'll just take a screenshot.
