They don't want to look like grifting influencers? The backlash was long overdue...

"Just"

I hope you at least got paid for that advert...

I saw a post with Guardian(?) article about it a few days ago, and yes it's apparently to not look too professional...

"Funny" that the lawyers didn't deem suddenly necessary to cut the description of Biden as a senile old man in the same sebtence...

The exact phrasing (part of the same sentence as what was cut, in fact) is "an elderly man in obvious mental decline"

Bingo! The BBC is not scared of him like it suddenly is of Trump

These are largely rhetorical questions, btw. It is quite clear that the answer to both is that the RW press' campaign and Trump's threats have succesfully created a chilling effect at the BBC. It's running scared.

*clutches pearls*

Why did they keep the bit where he says Biden was a senile old man, then?

Now you're just repeating what I've just said but omitting part of my argument to suit yours...
I think I'll leave it here.
