I couldn't agree more with what this guy is saying. But, mobile applications aren't actually the worst offenders here. At the very least, both platforms have their guidelines for developers to follow if they want to make their apps consistent with the rest of system. And I wouldn't be so sure this is not important: snazzy looks might gain you more installs, but UX that silently and subtly uses established patterns fits more firmly into users' minds and may noticeably increase retention (and thus number of positive reviews). The bigger culprits in terms of violating UI consistency are, I think, web applications. As far as I know, you don't even _have_ any definite guidelines there to begin with, which is of course due to decentralized nature of the web ecosystem. There are some effort that encourage consistency as a side effect (Twitter Bootstrap comes to mind) but the decade-old habits of designing every website completely from scratch do not seem to be dying anytime soon.
