I'm very outraged that you are right. Just checked with a dubious app that let you display current clipboard with no user action.

Yet you still have to bring the app to the foreground, but this is potentially a huge privacy leak IMHO.

The "doodle fruit ninja run" game I play don't need to now that my girlfriend left me so they can display a tinder ad...

(Oh, god if an evil ad developer come here don't take this as a good idea)
