No, it does not. It’s pretty clear that whatever Hive is (as well as other content silos), it uses the Internet to communicate with the mothership but does not meaningfully participate in the World Wide Web (aka the web). The article speaks of this exact scenario.

No, he is not confused at all. He's specifically railing against walled-garden, closed services where your only access to them requires a mobile app (which of course uses the internet), and has no (or limited) web-based functionality.

(Also note that this is Jamie Zawinski, who wrote the UNIX version of Netscape in the 90s. I don't think a guy who wrote a web browser would be confused about the difference between the web and the internet.)

He repeatedly says “only use one that is part of the world wide web”. I’m not sure how you got from that that he is confused. Also it’s kind of funny that someone would think jwz would make that mistake.

He said that mobile social apps that don't have web presence hate the internet. These apps don't hate the internet because without it they wouldn't work. The majority of people use mobile apps instead of websites for social apps so it is not a big priority for these apps to invest in recreating the app on the web.

The Internet was created with openness and interoperability in mind, so although I may not agree with some of his most extreme opinions on other subjects, he's spot on when he criticizes the app-only approach. A lot of services can be accessed only by phone apps, the reason being that mobile platforms aren't "plagued" by open protocols, so they're easier to monetize because there's no open competition.

No, they want people to use the app so that they could be tracked better.

An example is reddit, which makes the mobile web experience awful to force people to install their shitty application.
