This idea is very common among the community. I paid for the games baaaack in the day (I even have a disk signed by ZUN himself) because shumps are my favorite genre and when Touhou 6-7 came out there was a huge drought. The games were good, I never particularly cared about the characters but the gameplay was solid and interesting, with good scoring mechanics and some spectacle despite ZUN's terribad art skills.

This was a huge hot take apparently and members of the community hated everyone who obtained (and played) the games legally. You'd get bullied relentlessly for it. And I don't mean "guys you gotta buy the games to support the artist" or any form of moralizing, just mentioning you purchased the games got you unreasonable amounts of anger. Even friends from Japan who bought extra stuff like the music CDs and stuff made them so angry that my friends got banned from the IRC channel and forums. I left after that because that was unsustainable, people were only there to discuss fanfics of the characters and porn.

I still like the games, but the community at large is disgusting and hate people who actually play the games. Triple so if they are purchased. This guy is the perfect representation of that attitude.
