I've basically given up reporting bugs with Apple as they just seem to be ignored and either never fixed, or fixed some years later when the corresponding component is completely rewritten.

I basically resent filing bugs with companies that have enough money to do proper testing, I don't want to work for them for free, especially if there is no answer, or a 1st-level answer who hasn't even tried the filed repro case. However, I am happily reporting bugs with open source projects.
