... why does Google drop bugs about MS at or before 90 days, while giving Apple 1+ year to fix bugs in past?
Microsoft appears to give the answer to that question itself in the blog referenced by TFA:
Windows is the only platform with a customer commitment to investigate reported security issues and proactively update impacted devices as soon as possible. And we take this responsibility very seriously.

only 10% of Tor users are journalists, human rights activists, etc. A bit more than half use it to hide illegal activities.
(Yes, TFA is about messaging, but the whole "we must save encryption to protect the downtrodden" meme is just bogus.)
You got it backwards. To make your point about bogus, you should look at the percentage of journalists, human rights activists, etc. being Tor users, not the other way round.
That's a straw-man. Amnesty International's is not arguing that these services should be anti-government, just that they come with basic precautions to ensure that communications that are meant to be private are actually private.
To put it as a car-analogy, I think Amnesty envisions (end-to-end) encryption in messaging being standard, a bit like safety belts are standard in a car.
