He definitely hasnt been underpushed....how many wrestlers have been pushed consistently harder than he's been? There's a reason why hes over.
Ive seen this with Benoit, Eddy G, Jericho....their fan boys are just so relentlessly obnoxious and over the top. They demand that their guy receive a push akin to a combination of Goldberg, Hogan, and Stone cold steve austin, and anything short of that is some JFK level conspiracy against their man. Its this idealization of their guys, where they have no flaws and are perfect in every way.
DBry was a ratings flop as a main guy, is poor on the mic relative to being the top guy, and looks like he works at Geico (minus the beard). But of course there is never any room to have reservations about an internet god being a top guy, or to critique him. Just give him the world or else.
The funny thing is that his most ardent supporters seem to spend so much time obsessing over his push, and bitterly attacking Triple H, Vince, Steph, and God himself every time he takes a drop kick, that they seem to miss out on actually enjoying the wrestler they have such unwavering adulation for.
