Hard to imagine anything new to add to a thread so polarised? But ... try this.
As I ride NOW - I would probably pull in and let the bus through. Silly - but a wee recompense for the number of times bus drivers have looked out for me. Around me, it's pretty rare to see a bus pull that kind of trick.
Five years ago, it would have beern different. And that nas nothing to do with me learning manners!
THEN - I'd have looked at the livery. Arriva or Transdev colours - I'd pull in, let the bus pass; cos their drivers were consistently superb.
First Leeds? I"d have done pretty much as this cyclist does (with a stronger position, I hope). Because in those days First still had a hard core of bullying fools. Knight of the road/cowboy - you never knew what might be driving a First bus.
To their credit, First management invested heavily in cycle awareness for their drivers - as far as letting the worst of the cowboys go. It took time - and a fair few videos like this, complaints, etc from cyclists. We we were lucky - pushing at an open door.
Bottom line - cycling is that little bit safer and more pleasant as a result. [the exception would be out the A660 corridor - heavily used by ... not-very-clued-up students on bikes, using very poorly implemented cycle lanes; and bus drivers getting impatient]
Lads and lasses with cameras were part of that improvement. Big or small - who knows or cares? But the knee-jerk "cyclists-with-cameras-are-nobbers" in some of this thread is misplaced.
