Why? What you described appears to be the safest place on the web.
A lot of servers still use HTTP, for various reasons. There are also some clients that can't use HTTPS.
If the same server has two domains associated with it, does it count twice? Now consider a loadbalancer that points to virtual servers on the same machine. How about subdomains?
In reality as far as privacy goes, the matters are on average opposite to your claim. Most sites that will put your privacy at risk today are using https - I am talking about the vast majority of the commercially operated web today. I know my privacy is much better respected on a plain text (no javascript) site using http then on [insert a top 10k most popular site here] using https.
And for security, if I am not performing for example shopping or entering my billing details anywhere on the site, I do not see how a http site can compromise my security.
I actually prefer deploying http sites for simple test projects where speed is imperative because they are also faster - there is no SSL handshake needed to connect.
This can be prevented by (a) using TLS1.3 to ensure the server certificate that is sent is encrypted and (b) taking steps to plug the SNI leak; popular browsers send SNI to every website, even when it is not required.
Of course, I'm fortunate enough to live in a place where MITM attacks are virtually non-existent, aside from WiFi portals and maybe ISP banners (which I've never experienced.)
I don’t know where you live, but i feel like this is more common and insidious than you think. For instance, in the UK Vodafone (or Three, I don’t remember exactly) would break 100s of our sites by injecting js and tracking pixels into the markup.
Now, with behavioural targeting slowly dying, ad tech businesses talking about fingerprinting as valid alternatives, and contextual targeting on the rise, I can guarantee you that the situation is going to get worse.
