With HTTP (cf. HTTPS) the user can easily control what is sent over the wire

I can monitor, filter and/or modify egress with a local network foward proxy, for example. I can neutralise or stop traffic I do not want to go to so-called "tech" companies based on its destination and contents, as opposed to "trusting" it simply because it's protected by HTTPS (including "protected" from review by the user)

This level of user control can interfere with the so-called "tech" company data collection, surveillance and ad services "business model"
