Bend over may refer to the action of bending one's body over, as in to pick up something, or, for example, as the hydra does in order to move when hunting, in dancing (like in the various breakdance moves), gymnastics, and sports (like snap football), as well as to be (vaginally or anally) penetrated in sexual activity.

so even if you took bend over literally there's nothing wrong (or anything implying anal sex) in saying that Mint guys bent over to pick-up Intuit's offer.
and while Jason Fried has actually added value by using such provocative but eloquent metaphor, Dave McClure has totally subtracted any little value that was in his rant by obscuring it with fucks etc.
