Why doesn't ATC like it?

Because it conflicts with San Jose's LOUPE ONE departure. The extra
three to four minutes hanging over the airport really ****es them off.
Especially since they're not expecting it.

Why wouldn't the controller provide vectors?

I don't know. Some of them are good about it and do provide vectors.
I suspect that the others aren't as familiar with the procedure turn
requirements as you are, so they don't see the need to do it.

You make it sound like it's a burden on them.

That's the impression I get. Its probably easier to give a one-time
instruction and then concentrate on talking to the airliners that are
getting vectors, than to make sure that the little single-engine
airplane doesn't get pushed around by the wind and correct the vectors,
then issue the turn to intercept at just the right time.

The way for them to avoid the procedure turn is to provide vectors to the
approach. The way for them to avoid providing vectors to the approach is to
accommodate the procedure turn. Those are the only options available, they
must choose one of them.

I agree with you, but in practice it doesn't always go that way.
