They're not saying it about every single dev though, are they? The sequence in question isn't just flashing lights that could be found in any game - it's nigh on identical to the sequence used to test for photosensitive epilepsy. That is, it's designed to induce a seizure.
My point is that, if a game has potentially epileptic educing scenes and DOESN'T have an option to remove that, they are seen as criminals? The outlash is stupid. Full stop. The issue at hand is genuine, but keyboard warriors over shadow the core issue.
As for 'designed to induce a seizure', are you saying that it's designed purposefully to cause people with epilepsy to have seizures? Because anyone making that claim is going down a very sketchy path which with a big enough public profile, is essentially accusing someone of a crime... Which in it's self, if the accusation is false, is a crime.
Again, a really sketchy line to walk. I imagine a warning will be apparent, if not, then that is the bare minimum should be in the game.
