Legacy media is panicking. They see their market share shrinking due to the rise of content creators on platforms like YouTube and TikTok. So in an effort to reclaim some of that, they're spamming the algorithms. But they will not even nearly as succesful as they hope to be. Younger generations simply do not relate to legacy media channels, even if they appear in their YouTube recommendations. The result is that eventually the BBC will panic even more and then come up with some other draconian plan.
All of those actions are driven by panic, and I think it's hilarious. Let's not forget that the BBC has a serious image problem, as throughout the years some higher-ups and some well-known faces are/were involved in some scandals, usually in relation to some weird rapey sexual stuff. And I imagine that especially Brits are tired of the BBC as many of them aren't even really watching anymore, while still having to pay for a mandatory (!) loicense.
