While we remain on the off topic, what happens if it is a private company providing a service that seems very similar to one the government provides? Imagine if eventually USPS went away, could FedEx/UPS decide to not do business with a group they didn't like (say no mail for anyone under 30)? What if all public libraries were eventually replaced by private ones and any pro-liberal material removed?

I think discussing Constitution protections from the government should include discussions on protections applying when the government allows the private sector to take over some of its work. If privatization reduces constitutional protections... that feels a bit like an exploit, not an intended feature.
