I mean... not really?nuTSR?
Again, they had other things that forced them out of business, including bad product and copyright infringement, but there was definitely some shouting down regarding their biases in their stuff. Granted, it was absolutely justified.
NuTSR wanted to put out a product that specifically appealed to a narrow sliver of the TTRPG community. They advertised that product as hard as they could, and had their preferred sliver of the TTRPG community backing them.
But that sliver wasn't big enough to support a company. They'd need to aim for a wider audience for that, and they weren't interested in a wider audience.
No one who rebuked NuTSR's nastiness and bigotry on Facebook or Twitter or whatever was ever going to buy their Nazi Pseudoscience Sci Fi book. And a lot of people didn't buy their "Goblins" game because it was poorly written and half-done schlock.
And they even had a successful Kickstarter for their Dungeon Crawl game from that sliver of the gaming populace... That they didn't fulfill at all, because they either pocketed the money and walked off or just didn't plan their kickstarter costs from the start and couldn't afford to fulfill their orders.
NuTSR failed because they were bad at designing products, bad at selling products, and bad at fulfilling their orders. Because the products were never -actually- the goal. It was to get Wizards of the Coast to buy the TSR brand name from them for millions of dollars.
Which was never gonna happen.
All the backlash did was ostracize them from the community they never wanted to be a part of, anyhow.
