Of course, this isn't shutting down Parler, it's about removing an app from a store. Cry me a river that they'd have to log in using their phone browser or something. And let's be honest here: even a platform under 230 is not immune to consequences for facilitating a coup or an insurrection, I would have to believe, though I am not a lawyer.
230 has a "Good Samaritan" portion. In simplest terms, if the platform does its best to remove illegal content, it's good. Parler is definitely not doing that.
Apple, as a maker of (very!) personal, general computers shouldn't have any say on what the computer users can or can not do once they bought these computers.
In fact, IMHO they shouldn't be allowed to control the App Store at all. (Of course this also goes for their competition : Google, Microsoft, probably even Canonical.)
