It's unfounded because HTC redeemed themselves with the M7 and M8. I had the Evo 3D, which wasn't too far off from the Thunderbolt, and I swore off HTC after that, but I ended up getting the One M7 by chance and I'm really glad I did. In terms of just the phones themselves, HTC bitch-slapped their competitors with the M7 and M8.
The Thunderbolt had a glitch where it would send a text message randomly to any person on your contact list.
AGAIN...
...a glitch where it sent ANY message to ANYONE on your list in no specific order. They never fixed this properly.
That is just one of the many awful things HTC did.
HTC didn't even bitch slap the superior S5 (outside aesthetics). Which is what I'm rolling with now, so they have some work to do.
