Linux didn't have that problem, a single vendor did. You could say the same for Apple except they are the single vendor. That stupid security trick in Ubuntu only impacts subset of a subset of Linux _desktop_ users which is a pretty small subset of computer users as a whole. When Apple does something like this, it impacts a much larger share of the world population.

So how about we keep the snark to an appropriate level based on the impact to the world population? ;)

These sorts of bugs can happen anywhere. We all need to bear that in mind.

One notable difference, though, is that macOS is proprietary software. Apple have sold their users a product and haven't respected their users' right to use, modify & distribute that product; their users have never had the ability to inspect the macOS source for this kind of problem. Thus, responsibility for this disaster rests solely on Apple's shoulders.
