The formerly decentralized services are no longer so decentralized since "free of charge, paid for by data and ads" has shown itself to be a viable business model that users love. (Until they understand what's happening, at least.)

People keep saying this but to my knowledge email still isn't centralized. While there are a lot of gmail users in the US but that's not the case in many other countries, many people also have a .edu email and a few years ago I ran my email server myself (I even handled signing papers when I switched jobs over it.) Google even contributed to and pushed for dkim and spf which solved a huge spam problem that threatened their ability to forward mail from smaller outside domains to their users. A lot of people might use one of the big services but as long as you don't have to in order to interact with them it's not "centralized."
There is no control within Facebook's ecosystem. Similar with AOL, if you don't use Facebook, you're necessarily out of the loop, and I don't feel comfortable with that.
Not to detract from your point, just thought you might be interested to know that USPS actually has a legally-protected partial monopoly on the right to carry letters (18 U.S. Code § 1696).
An exemption was added in 1979 allowing private carriers to deliver "extremely urgent" mail. This is why UPS and FedEx express mail envelopes bear that text on their front.
Apart from this exemption, USPS, FedEx and the like are only allowed to deliver 'parcels', not 'letters', though I'm not sure where the distinction is legally defined.
