I didn't find it rude at all. The comment that presented the link was pure click-bait. I prefer it when a brief explanation accompanies a link, especially when the link points to a 3 hour long video, as in this case. The YouTube teaser says "explores the workings of the human mind, intelligence, consciousness, life on Earth, and the possibly-simulated fabric of our universe". I certainly agree that the topic sounds interesting.

If the topic sounds interesting it‘s not click bait, it’s a good link that OP went of their way to share, we’re not entitled to anything

I didn't know anything about the topic before I clicked the link. Nothing in the comment that introduced the link revealed anything about the topic. And I only clicked the link because I was intrigued by the discussion here about rudeness. I was not motivated to click by the suggestion that watching would be worth my time (without any further details). That I found the topic interesting-sounding came after I swallowed the bait and clicked. Such things happen sometimes. And I still don't know if it actually is interesting, I won't actually know until I have set aside 3 hours to watch the video.
