To an extent, yes,
some of the arguments absolutely apply to other platforms as well. But others don't. You never saw such platforms directly impact elections as much, having Russian operations have as big as an impact as they have had on TikTok in e.g. Eastern Europe. Of course they tried running campaigns in the past on Facebook as well, but not with as high of an impact, and after they got caught the platforms have put in a reasonable amount of effort to crack down on them. TikTok knowingly turns a blind eye, and unlike with the US platforms, Russia can be much more blatant.
Think it would be pretty reasonable for other countries to ban such platforms too though, as China has understandably already been doing for over a decade. Facebook of course played a big role in genocide in Myanmar, so I wouldn't dare say the US platforms are necessarily better.
