Huh? HTTP is certainly an application protocol: you have a web client talking to a web server. The application delivers web pages to the client. It is by no mean an “agnostic” protocol. You can, of course, use it to deliver binary blobs, but so can email.
HTTP is used for many things, many of them unrelated to the Web. Due to its popularity, a great many things have been built on top of it.
The point I was making is this: when a server exposes an HTTP API, that API is the protocol, and HTTP is a transport just like TCP underneath it and TLS on top of it. The equivalent of a protocol like SMTP on top of TCP is a documented API on top of HTTP. The use of different terms confused this conversation.
But that’s a bigger and a different discussion than talking about interoperability. HTTP is still an open protocol with open-source implementations available at both ends.
My point is, you can’t interoperate with Facebook or Gmail or Reddit just by implementing HTTP; you need to implement an API or “protocol” to talk to them. And if they don’t have one—either deliberately, or because their HTTP traffic just wasn’t designed for interoperability—then there is no open “protocol”.
The great majority of ads are delivered in browsers which are NOT restricting the “user’s control over their experience” and which are freely available as “competing open source clients”.
The great majority of web ads are actually displayed, keeping revenue flowing. They’re not removed by adblockers. Even if everyone installed adblockers, I believe ads would win the ensuing arms race. It’s much easier to scramble software, mix the ads with the rest of the web site so they can’t be removed without breaking the whole site, than to write a program to unscramble all websites. (In contrast to the problem of unscrambling a specific given website, which is pretty easy—as shown by the history of software copy protection.)
That is only true because the server provides the client software, i.e. the website’s client components. That the browsers are open source is as irrelevant as that the client OS is. The actual application that’s trying to enforce showing the ads is the website that runs in the browser.
FTP for example.
The amount of use FTP sees today is completely negligible compared to its market share twenty years ago. But I agree, file servers (and p2p file sharing) are good examples of an area where most protocols are documented and interoperable. (Although in the case of SMB/CIFS, they were documented only after twenty years of hard struggle.)
Why is that a problem? If they can’t survive they shouldn’t.
I didn’t say it was a problem…
The before-the-web internet did not have a business model where users paid for service. It pretty much had no business model at all.
That’s not true. There were many services being offered for money. Usenet was one. Email was another, before the advent of ad-supported webmail.
