On the contrary, I'm glad they aren't throwing money at this.
Throwing money at things sets a precedent; if they let things run as they are now, it's quite possible that the bill will fail (like SOPA did) due to public outrage, not due to money.
The fact that politics is powered by money in the US is terrible, and the more exceptions there are to that, the better. I think this can set another precedent.
I think the big tech companies should only toss money in if the current efforts fail, as a matter of efficiency, morality, and precedent.
