I think this is a pretty common approach to "free speech" by people who don't really understand what censorship is, and/or are not capable of empathizing with others. It just never occurs to them that when you claim free speech as a basic right, that means that other people also get to speak. It would be funny if it didn't create so much harm.
IKR?! I personally don't bother arguing with game designers unless they seem sincerely interested in feedback, because a game with unreadable text isn't fun for me, and I try not to waste my time playing or discussing games that aren't fun. If the designer wants to limit their userbase to people who are willing to read cutesy fonts, that's their problem, not mine. And I suspect it can be a problem when they already have a small userbase, and they make a design decision that alienates some of the very small number of people who have heard of their game.
But in education, or with user manuals, or any number of other products that are hard to replace... yeah, graphic designers should not get the final say when their opinion is that aesthetics are more important than accessibility. If I can't read the user manual, website, or whatever, I am going to call customer service, but not everyone has the time or comfort level with phones for that workaround.
The court's decision is good news, but what the ever-loving fork is wrong with Florida? Other than RdS, of course, but I kinda doubt he could do this all by himself.
