Personally, I've never actually heard this problem. Do you watch industry-specific videos in a non-anonymized browser session enough? Once you watch, like, 5 videos on topics you care about, the algorithm has no shortage of astute suggestions.
I think they've jumped the shark and need to give me more control because currently I actively avoid watching videos I think MIGHT be interesting because the risk is too high. This is a terrible position to put your users in both from a specific experience perspective but also in a "how they feel about your product" perspective.
You can remove videos from your viewing history. I do this when I start watching something but the content turnes out to not be what I expected. It seems to prevent polluting my recommendations.
