While I agree with you that it is "weak and entitled" at least to some degree there is ample precedent to support the "everything must be still and quiet" interpretation in regard to distractions and dg.
And a sort of key here is this: "...those out of your control..."
I've read all the complaints, and I know you've all been sworn...
Look, the simple truth is that the cameraman, while certainly trying to do a job, is also (presumably) well-versed in the general rules of etiquette in the games (both types) of golf.
If he isn't, he needs to be. Stat.
Assuming he does understand these simple, sometimes unwritten rules, then he was 100% wrong to deny the player her request. Period.
Without the player, he has no job.
As to ru4por's "out of your control" qualification, most would agree. But the young lady does have some control here. Or should. It's one thing to talk about outside traffic, crowd noise, birds, whatever - things that could reasonably be ignored.
It's another thing entirely to bring a human, who should know better, into the mix. And again, if he
didn't know, her request should have been like a slap in the face. I don't blame Catrina at all for not only struggling in the moment, but also for continuing to struggle, if that's what truly went down.
But the loitering behind the basket in her line is not something we should expect, or have to deal with - especially if we ask a spectator to move - in a tournament scenario. Don't get pedantic: the cameraman is like Spectator-zilla.
