An app can control which HTTP library it’s using and even bypass the built in one on the mobile device. That’s not possible in the case of TCP.

So no, it’s not the same.

Another issue they mention in the article is middleboxes, which basically will never be upgraded, and will never support new TCP features.

Nor will they support new HTTP-features.
