Yeah, we shouldn't fall into the trap again of thinking of the BBC as a homogenous blob. It might be inconvenient for the bean counters if we win again, but BBC Eurovision team have made it pretty clear they are intent on winning and hosting again.
Besides, the way the BBC threw everything at it in 2023, when they technically could have said no, really ought to have dispelled any fears that they don't want to win. In recent years they've finally realised what a huge draw the contest is for younger viewers, and these sort of live events that brings the country together are what gives the BBC a purpose in the streaming era.
It annoyed me when they used to say "we're aiming for left side of the board". You need to be 10th best to score a single point. If you aim for 13th you deserve to come 26th.
