No, but anything can be grounds for a lawsuit as long as you have enough money to throw out. And given that they are being sued by the government, all bets are off.
That’s my whole point, none of the provided arguments are a good reason for a lawsuit. This has early 2000s “It’s those darn videogames” vibes, except this time instead of saying that their doing it to protect our children, they are openly doing it to get the money.
