I have a very, very limited understanding of the subject, so take this with a lethal dose of salt, but I’m under the impression that the US healthcare system is an absolute minefield, and not everyone has equal access to it, even via insurance, in the ways you might otherwise typically expect.

I only use it because there’s no way I could convince my friends and family to move to anything else.

There’s no point in switching to another app if I then literally couldn’t communicate with the people I need to through it.
