Some people maintain that JavaScript is evil too, and make a big deal out of telling everyone they avoid it on moral grounds as often as they can work it into the conversation, as if they were vegans who wanted everyone to know that and respect them for it.

So is it rational for a web design company to take a moral stance that they won't use JavaScript?

Is there a market for that, with enough clients who want their JavaScript-free work?

Are there really enough companies that morally hate JavaScript enough to hire them, at the expense of their web site's usability and functionality, and their own users who aren't as laser focused on performatively not using JavaScript and letting everyone know about it as they are?
