No I don't. Not many people care about there privacy (otherwise facebook would have been bust). And even if they had pledged 200% or 300% that would have been enough to send a strong signal but 1088% of pledging is just not right.
There could have been so much more done with the other 80k. So many other things need money.
I don't know if it is not 'right', the signal function would have been just as strong if they would have set their original goal at $100K and people would have sent them that much $.
In some ways the $amount is a value that collapses a number of underlying elements to a single number, the amount of frustration around facebook privacy, the people that simply wish these kids luck and there are a number of people that hate facebook enough to put up a substantial amount of $.
Which portion of that $100K ($109K already, $4500 per hour right now) comes from the 'signal' portion is hard to tell.
