My question was whether this is only a problem on iOS or also Windows.

With the advent of the iOS 14 beta, well-known apps have been recently
publicly caught and outed...

Each time they're caught (so far anyway), the company immediately says it's
a nasty bug, and then immediately vows to remove the reading of the
clipboard on every keypress.

o *iOS 14 - Linked-In app caught reading the user's clipboard in background (including from other sources)*
https://groups.google.com/forum/#!topic/misc.phone.mobile.iphone/2VZ5a3QsvBc

o *Reddit caught red handed by iOS 14 copying the clipboard contents on iOS devices*
https://groups.google.com/forum/#!topic/misc.phone.mobile.iphone/-gvgKjTALvI

o *iOS 14: TikTok seems to have been caught abusing the clipboard in a quite extraordinary way.*
https://groups.google.com/forum/#!topic/misc.phone.mobile.iphone/dRKgQG8jGo8/

o *Famous iOS apps are snooping on the Pasteboard - Learn Worthy*
https://groups.google.com/forum/#!topic/misc.phone.mobile.iphone/XXaeEvEB79Y/

o *Even more iOS apps caught snooping clipboard contents ...*
https://groups.google.com/forum/#!topic/misc.phone.mobile.iphone/IHVirXnbJF0/
etc.

For example, here's just one snippet from just one article cited above:
