The (great-grand)parent is probably not talking about EV certs, because then they'd be stupid. They say:
> We could've had a mostly encrypted Internet a long time ago if encryption and privacy were not hitched to a commercial identity certificate with crappy maintenance tools.
...which wouldn't make sense if it didn't include the basic DV certificates, because then those DV certs would be exactly the sort of quick&easy encryption-without-identity they're looking for.
They're complaining about encryption requiring a process that used to cost enough to discourage many people, even for DV certs. The situation has only really changed in the last two years or so with LE, and you can quite clearly see the impact of free certificates and a slightly better process on the rate of encryption.
