Microsoft did and does today. Personally, I've submitted 6-7 bugs to them over the years, for Windows and other products, have gotten patches delivered in weeks, and rolled into a normal update roll up on 3 occasions. With a security issue, the program manager for the product called me back personally and arranged to have engineers onsite work with our folks in mitigation.

Having a support contract helps a lot. Apple doesn't really even offer that.

With one fairly epic failure from them, my employer was big enough to get a sad Apple guy to fly up and express his heartfelt sorrow. Very touching. His SE helpfully suggested that we restore our phones (15,000 of them). That was about the extent of it.

It's just their way, each vendor is uniquely obnoxious. But the unpredictability limits what you can do with their products.
