If I had to guess I’d say because “an unknown man” can be intepreted as “an average man” which obviously is going to hit a lot of people.
The actual statistics of man vs bear is not really the point through, and a large number people did not get that. It’s just that the question was phrased (intentionally or unintentionally) in a way that lends itself to this comparison.
Same setup as you, fan and NVMe and I can play 720-1080p video without any issues from all of the streaming platforms I’ve tried so far as well as local files. Also streaming 1080p 60Hz gameplay from my gaming setup over LAN with no problems.
