Microsoft is an actively anti-conservative Big Tech company, so those who already dislike Big Tech organizations and conservatives in particular who are tired of being targeted for destruction by Microsoft and others - are already in a howling mood. A vulnerability is just icing on the cake for more howling.
Linux firms are generally what you would call Little Tech and don't single out conservatives for harm. Many times there aren't even any Linux firms at all, just large groups of dedicated software developers trying to create something that(among other things) won't spy on your every move; because, these developers don't want to be spied on themselves and have the power to be not-spied-on with their own creation.(vulnerabilities aside, of course)
Your first sentence is a bit bewildering. I’ve been in IT security for 10 years. Do you think that vulnerabilities are all uncovered by accident in the wild?
