Want to replace a ceiling fan which has a remote control. I unscrewed the
three (on this model, there are only three) screws at the top of the
canopy. It twists an inch to each side, but won't come down. It looks like
the metal inside the screw holes (what the canopy screws into) is also
moving. How can I get it unstuck? Twisting over and over isn't helping.

If you are replacing a ceiling fan with a ceiling fan, I sure wouldn't
take it down with a crowbar. Ceiling fans are heavy and have to have
a very secure box.

What is wrong with reading the instructions?

A picture may help.
