> Someone asked a question on reddit, and you're trying to push it hard as a rumor

I am simply providing information to the best of my knowledge - it's the title of the post. The caching issue is also a guess that no one can verify yet.

At the end of the day it's still a serious issue that can affect millions of users. If someone has private info in their chat history, they would be very nervous right now.

I'm surprised at seeing the parent so highly upvoted as well. There is no "rumors about hacks/leaks" just because some random comment of Reddit.

Actually, that sounds like the literal textbook definition of a rumor to me
