I suppose some of the "no sales to CA" is a form of protest from the dealer.

Some of it certainly can be attributed to dealers not being able to cope with yet another law in their highly regulated business. Unfortunately, some good people of simple background are overwelmed with the large variety of gun laws governing their trade. They sometimes simply shutdown to what they know works and stay within a 'safety zone'.

But, as a California resident (albeit born in the midwest, but 40 of my 52 yrs has been in CA), I'm disappointed that some dealers won't sell to a CA resident.
