Also... http?
Also... http?
One example of what can be done is to cause the users to DDoS a third party.
But I admit it's a valid reason to have https.
Hackernews is a global website last time I checked so even if you don't face issues like that, many other users might.
Not sure why you're talking about HN though, the website in question was not HN.
By using http you are assuming your "here" (where ever that is) is the same as where your readers are.
And if your "here" is in the US then hotel WiFi providers in the US are well known to have done MiTM to insert ads.
The man-in-the-middle attack potential other replies have mentioned is possible, but my reason is far simpler. Defaulting to https for everything removes the cognitive load of having to decide whether to trust a website and pushes users to believe everything should be secure by default. The environmental impact is, in my opinion, worth it.
