Control Panel for Twitter also has an option to hide Blue replies in threads, but it's off by default as you can end up with hundreds of replies "visible" (as far as Twitter's windowing implementation is concerned) on the screen, which tanks performance.
Tweet threads seem to top out at just over 200 replies, so boosted replies make looking at most "popular" tweets pointless, like anything from ${siteOwner} with thousands of people trying to engagement farm for Blue Bucks in the replies. You're lucky if more than 5 non-Blue replies are left standing.

You can also hide the idiots with the BlueLiteBlocker extension

Makes Twitter a bit more like it was before idiot in chief took over
