I remember waaaaay back in the day when Tom’s Hardware was mocked as Tom’s Hotware because they did some testing of what would happen to AMD and Intel CPUs if the heat sink spontaneously fell off while they were running. I think at the time, the AMD CPU melted itself, which Tom’s Hardware criticized. It did seem back then that there was a subtle anti-AMD bias on the site, but I haven’t paid close attention to it over time. It’s interesting to hear that the accusations of Intel bias still exist!

Gamers Nexus also showed in their video that TH's writer was the moderator of intel subreddit and they had been deleting posts on the recent issues with intel CPUs.

That is interesting. Between Anandtech and Tom’s Hardware, I am sad to see that Tom’s has ultimately survived longer. Anandtech was one of, if not the, best.

To be fair I've accidentally run a CPU without a heatsink and it did a thermal shut down while testing a BIOS issue. It's a useful feature.

That was fairly standard startup behaviour across all makers. The comment you're replying to talks about the heatsink suddenly falling off - a very specific testcase seemingly chosen to make a company look bad.
