It is, and the iOS 14 changes fixed and highlighted the issue.
Perhaps naively, but I give all the apps (even Tiktok) benefit of the doubt here. It was a fairly common practice for podcast apps (for example), to check the clipboard for an RSS feed and prompt to subscribe to it when adding a podcast. iOS 14 gave new APIs to do that in a more privacy preserving way.
I don't think anyone was busted for anything nefarious, but it just reavealed a lack of suitable APIs on the platform.

How annoying! It would be better to register an rss:// handler and let the OS notify the user that a new RSS url has been found {on the clipboard, in html, text file, url, whatever} and ask what to do (perhaps with some automatic permission to send it to your app).
And where it is, there's so much more that's also illegal that just about any nasty thing can be hidden between the trivialities of the resulting consent banner dance.
OS level protections are truly the least bad thing because they can also set arbitrary thresholds that would be impossible to define in law.
On Android this was "fixed" in newer versions. One of my apps used to use the clip board but it is no longer possible to listen for the content unless your app is in the foreground.
