We didn't need to deprecate everything that isn't encrypted. Encryption isn't some panacea that'll fix all woes. Much of it, like SSL, is little more than transport security or snake oil. Do you know what Verisign did to verify that cert? Do you know how many CA's have been compromised and probably still are? Encryption is only as good as the trust it engenders and the functionality it provides.
Having my DNS queries encrypted is very low value. It just seems like one more tactic by large companies to squeeze out small companies, much like DKIM. It's got marginal value and "solves" a problem that spam filtering already took care of decades ago only to make it harder for small server operators so they'll hopefully throw up their hands and give the business to Google or M$, instead. That's what they want, not "security".
