In fact, r/btc is controlled by for-profit entity (bitcoin,com which has little to nothing to do with Bitcoin the project) and has advertisements blasted all over the subreddit page.
It is the furthest thing from a lie and can be verified by anyone who wants to try posting to both subreddits. Anyone can also go to a site that shows deleted comments and see the discussions that get deleted on /r/bitcoin.
That's an obvious lie, people payed by blockstream directly or indirectly have been in control of the sub for years, deleting any thread or comment that contradicts the narrative they want to push.
This is a well worn topic and I think you know that. Surely you realize that anyone can google bockstream takeover on reddit, but are counting on people not doing research.
