Constructive Dismissal [0]
If you quit, know that it is likely exactly what your boss wants.

I would never advise someone to keep working a job that takes advantage of them, just to spite someone else's wishes. If they are a bad company and make you work overtime for substandard pay, who cares if they're happy to see you go? Go, and shake their dust from your heels as you leave.
I don't know the OP's particular situation, but constructive dismissal can be very relevant when someone is pushed out of a job where they would otherwise be expensive (e.g. severance) to terminate. This is what constructive dismissal laws are in place to prevent.
In either case, as you say, the right thing to do is quit, but the OP should be aware of the laws in their jurisdiction, in case they have a case worth pursuing.
Judging by the OPs one other post on HN that they could give up 20 hours of time a week it would also be difficult to get some people to accept that the OP was fully motivated in what they were doing and working their hardest.
I'm not a fan of burning bridges, BUT: I'm no lawyer, but if your pay cut is immediate I cannot see why you can't also leave immediately. If you are in a place with a buoyant job market the most satisfying thing to do might be to just not go back to work and get another job (assuming you can afford to survive the time that might take). Even if your employer does want you out, I bet they aren't prepared for you to leave immediately, a little bit of payback that may cause them a lot of stress and not much for you (although a bit like constructive dismissal, doesn't do your reputation a lot to good).
