Interestingly I think this may have been on certain spheres. For me, I only heard about the dangers of this game to people who are photosensitive or have seizures triggered by flashing lights, and also complaining that Cyberpunk 2077 reviewers without glowing reviews were facing harassment.[0]
However, I'm not a gamer, I'm a science fiction writer who follows a lot of disability advocacy, so my spheres may be very different.
Unfortunately you're right. "Gamers" are a fucking wierd bunch, they'll send death threats to reviewers who dare not to give "their" game glowing reviews. The one you mention had "gamers" literally replying with GIFs and videos which could trigger a seizure.
I use gamers in quotes because it's obviously not every gamer who does abhorrent stuff like this but it is certainly an issue within the "gamer" community.
The game was released on Thursday, the epilepsy-inducing flashing (during braindance activation) was fixed on Sunday.
It was nowhere near the 80s/90s japanese cartoon flashing, basically two white lights flashed in alternating patterns for 5 seconds on opposite sides of the screen. In the fixed version, the light is static.

[0] The author who pointed out that the game gave them a seizure later said they were facing harassment for it. https://www.gameinformer.com/2020/12/07/cyberpunk-2077-epile...
