IMHO, not really caring about what other people think is part of the foundation of pinball, whether playing, collecting, homebrew or working in the industry. Either you get pinball or you don't. Some people are just joyless in their lives and they choose to crap on those who have found joy and enjoyment in their hobby or work or . . . .
Right now pinball collectors are having a much easier time staying sane during this pandemic than most others.
