If by conservative you mean antisemitism, white supremacy, far out conspiracy, racism and hate speech: then yes they banned 'conservative' platforms.

That's trying to make a cultural war of broadly accepted, democratic values. It got nothing to do with progressive politics.

If you want to go full libertarian and demand Apple to give freedom to all these medieval hate platforms, you'll have to allow IS and the Al Qaidas of this world their jihadism videos too.
