I mean you are assuming the person who is trying to murder you is a rational actor but you can't really be a rational actor if you are threatening death to someone because of their shit monetization policies on your entertainment. Hell some people throw "Death threats" at people because they decide to change a reload speed by a fraction of a second. So yeah "gamers" can be quite unhinged. Hell you had idiots in Jan 6 who loudly stated their intention and beat a cop to death. Hell we have seen situations of weirdos getting close to celebrities (in their heads) then trying to kill them, and I imagine cases like that will only get worse with parasocial relationships getting a bit out of hand with modern influences and streamers.

There might be a reason people freak out about death threats...

That's the fallacy of trying to understand criminal acts. For the most part, if someone were as smart, logical, and thoughtful as you are when you imagine the best way to commit murder, the kind of person to actually try and commit the murder would not be as smart, logical, or thoughtful to have gotten into that situation in the first place.

There are exceptions, of course, but it's enough of a possibility that it's probably better to take them seriously than not.
