> You don't need to trust any particular browser here.
You do need to trust that the particular browser you are using supports preloaded list, and is using the latest updated version of the list, and is not missing any entries!
What you're trusting the browser for there is the extra protection that preloading provides, but that's not the whole benefit here. The larger benefit is that it makes it infeasible for services to neglect to support HTTPS. So, even if your browser's preload list is busted, the site will be guaranteed to support HTTPS because of this effort, which you'll still benefit from.
Ah ok. I think I see what you are saying now. As long as a sizeable portion of browsers support a fresh version of the preloaded list, there is sufficient customer feedback to push the servers to only support https. Right?
