Lots of possibilities who "that guy" might be. "Professional musician"... really?

"Professional musicians" calling people "freeloaders" because they want to share music, ideas, as a part of a community with a common interest.

Its quite honestly anything BUT professional.

I see it as a person who likes to slam other people. "That guy" takes pleasure in criticizing people. Couldn't keep their sarcasm to themselves. Wanted to get out there and spread it around.

"Professional" is the LAST word I'd use to describe another person that publically calls out people as "freeloaders".

But thats just me...
