>The value of certificate authorities is to be the roots of trust, as said. But they aren't, DNS is. That's my question. If someone controls my domain, they can point it wherever and get all the Let's Encrypt CA signed certs they want. So how exactly is the CA being a root of trust there if the CA itself is basing trust off of domain control? In neighbor comment it seems that maybe the CA is basically acting as a hack to bypass an inability by clients to check DNS? I can see why that would have some practical value in the near term but it'd be good to do away with it as soon as possible. Apple/Google/Microsoft (and maybe Mozilla) may be in a position to do so if no one else.
