I would rather them push out updates as soon as they are ready. Not wait for the other OS to catchup.
Missing the point. The question is, why does it take weeks for the other OS to catch up? No one says they should hold off one for the other, but they darn well should fix both of them at the same time ASAP, especially since they highlight the vulnerabilities fixed in one in the release notes leaving the other in an even more compromised position.
It's like saying: Hey I have two houses, I realized both have windows that don't lock properly but I fixed one of them, hackers. I will fix the other one in a few weeks time. Play nice.
