If you think words gaining new and changing meanings is "a sad travesty", then I think you are a nice person -- and I don't mean in the modern sense of the word.
I don't know why Weird Al thought that was necessary, but this supposed less vs fewer "rule" does not describe actual modern or historical usage. Self-appointed grammarians can choose to stick to whatever usage they like, but going around with stickers and marker pens only makes them look like pedantic bores.
No. I'm saying it's fine for people to stick to the usage they prefer, which may organically bring about a change, but there's no need to be critical of other people for using what is a commonly understood usage.
That means they do have meaning. I'm sorry if you had trouble understanding the meaning of the words in the post. I think everyone else got it, though.
I think these battles are worth fighting. As does Weird Al: https://www.youtube.com/watch?v=RGWiTvYZR_w
