Couldn't be more true.
Was there an HTC phone that didn't have issues?
Nexus One: They probably used the worst touchscreen/digitizer that was on the market and didn't even set the capacitive buttons right.
EVO 4G: Out of memory all the time, thanks to Sense. I have to walk my mom through this weekly to help her fix it.
Incredible: Same issue, even worse, and they shafted everyone on the battery even though it could have handled the same one as the EVO 4G.
EVO 3D: ttttty camera (not just MP, but quality overall), zero support, horrible touchscreen that broke down for many, and they haven't updated it like they should have. Oh and they crippled the unlocking on it for most people.
One X: Good hardware, storage capacity of Apple's top phone from 2008.
EVO LTE: They didn't do their homework and shortchanged it on memory when they should have known that S4 (high video ram stolen from base ram) + even more bloated sense + many bloated HTC background apps + aggressive settings = a horrrible experience.
And just in general HTC has been bad about releasing source, fixing issues, and generally once you buy their phone you are screwed and left for dead. It's no surprise people wouldn't support getting burned again and apparently I'm one of the rare few who have bought an HTC phone more than once (Nexus, EVO 3D, LTE).
I can definitely say never again. I'd buy motorola or Sony before I bought another HTC
