HTTPS is indeed more secure for users, but it does have some cost, and I think OP has a sensible argument.
If you really think HTTPS is the best thing ever and is absolutely better than HTTP in every sense, you're just looking at it superficially.
When you start looking into how the entire Internet works and what role each party plays in the ecosystem, and how much "real" power each party has, you'll find that HTTPS is THE biggest centralization force of the web. If you think centralization and oligopoly by big tech companies is awesome, fine.
But there are people who don't like that direction for a good reason.
