I have news for you: the 1st Amendment doesn't apply to private organizations. It is governmentally stipulated proscriptions of expression/speech that the 1st Amendment says are impermissible. A private organization like a web hosting company is limited only by its own terms and conditions, which customers must agree to prior to the company hosting anything on the customer's behalf.
Give that is the way the 1st Amendment works, no First Amendment rights were even slightly infringed, let alone destroyed. That some organizations lost their hosting has zero impact on anyone's 1st Amendment rights.
