Having played in an era when OL blocking was cut blocking, I've always found this line of criticism a bit silly.
If you want to see some cut blocking at a level of expertise and effectiveness that makes Tech look like amateurs, dial up a film of the first Orange Bowl game between Bama and Nebraska. The Huskers outweighed the Tide by almost 50 lbs a man in the OL v. DL weights. Bama cut them (no pun intended) to pieces. That Bama team was the outfit where Cecil Dowdy was an all-American OT at 6'1", 215. When I was playing ball, blocking like that was the gold standard and everyone did it. (Mind, I hated Bama then and I hate them now; this is a technical point.)
Nowadays, it's different, mainly because they changed the rules to allow blatant holding - shoot, tackling - by OLs. We do plenty of that, but we also cut block more then most teams. So what?
