They don't, though. Gene is a very skilled drummer and able to make far more tasteful and musical drumming than they could just programming into a machine. If you've ever seen his DVD, the amount of little things he does to add taste (He's huge on the word "taste" in his drumming) to even blast beats; for example not only hitting in the center of the snare to toy with the amount of ring, or accenting certain hits on the ride cymbal.
I'm not saying he didn't play mechanically, I mean that's FF's style, but Gene adds a lot more than a drum machine can do. As for the other two bands, well... they're industrial-tinged. Duh. That's what they do. It's like saying no one complains about an electronica band using synths. That's kinda the genre.
I was not a FF fan and Mechanize kicks my ass every fucking time. One of my top 5 from 2010. TI is ok, but not on the same level.
