Because the user experience sucks. I hate copying a URL and have a bunch of meaningless garbage included in wherever I paste it, as happens with pages that leaves UTM artifacts in the query string.

I don't care at all about the tracking aspect of removing UTM, I care about how it makes the internet shittier to use.

This spells out the issues really well (with a funny video) https://wistia.com/blog/fresh-url The suggested solution on there "Fresh URL" is interesting, although it's throwing more javascript at the problem.
