And that’s a bad thing, and the people involved in making those sites should feel bad and do something about their mistakes rather than just shrug. And we should call them what they are: Mistakes, abuses of the web.
You have now stated that "those people should feel bad" for the second time. Personal attacks will hardly bring any change into this world. I'd instead suggest that you propose actual ways to solve the same problems that Javascript-based SPAs have solved which the non-JS web is still stuck with.
Just add a matter of precision, personal attacks won't generally improve the world on the overwhole aftermaths. But they do generally change the world into a less pleasant place to live in.
Sure, the people making these things should feel bad about it, and ideally change their choices... But if 5% of Firefox users can't use your page, and your page is important, they'll consider Firefox broken and go use something else.
Firefox isn't doing so well on market share, and appearing to be broken isn't going to help.
I made a web game that's simply not possible without js. Is it your contention the it simply shouldn't exist? Lots of people seem to enjoy it and I think they'd be disappointed.
