Again, I am not advocating for not having HTTPS so I don't know why you think HTTP+HTTPS is less private. It is exactly as private only it is also human readable and requires no centralized authority's lease to be visitable.
For example, the fact you are reading the wikipedia article on Tiananmen square incident might be very sensitive if you live in China (ignoring the part where they block wikipedia). Other places might object to various other speech, etc.
Although to be fair, the mass survelience threat model is probably less likely to have an active attack like tls stripping. But annonoyminity is all about hiding in the crowd; only securing the connection when you have something to hide from eavesdroppers means that you have no crowd to hide in when you need to.
