Artists have had their work paid for by patrons they didn't like for a long time.
Protesting silently is an old phenomenon. Frankly, if an artist was enthusiastic about every person who financed their work, I wouldn't consider them a professional.
I find that most people are not, when they believe that they can get away with it.
Professionalism is mostly about signalling to colleges, customers, bosses, etc. Similar to wearing pants. I wear pants in public and particularly to work because that is what professionalism looks like in my industry and society. When I'm at home, when nobody is paying attention to what I do, I kick off the pants and put on some gym shorts (even if I'm working from home).
