I would be more worried about slack remote connection policies.
This is true. And I am not trying to minimize the severity of that vulnerability. And certainly, Microsoft needs to patch it quickly. But realistically, how worried are you that this might happen with one of your computers? Or the computers belonging to your family, friends and clients?
That is, how many users do you know even have remote access set up? That is, to allow access from outside their own network? I think I know two, and both are IT professionals. How many users do you know leave their computers out, unattended and exposed where strangers or untrustworthy users can sit down at that computer and exploit this vulnerability?
So I think that illustrates my point, but from a different angle. That "security researcher"

had his little puerile tantrum because his reward was not as big as he greedily thought it should be. Yet we have to wonder, how serious, or rather how likely is it that this vulnerability will be exploited? How many users are likely to be victimized? I have to think it would be very few.
Now I don't know about others, or that security researcher, but a $1000 "reward" is not chump-change to me. This guy is not a Microsoft employee. He didn't risk his life or his own security. He was not hired by or contracted by Microsoft to find security flaws in Windows.
He did not
selflessly sacrifice anything! And yet he's so mad at Microsoft because they wouldn't give him $10,000, that he
selfishly and recklessly put others at risk!
