Valid concern, but that's a bit a defeatist attitude. Yes if we all switch to more secure encryption, they will try to crack or cripple those, but to crack 1024 DH was a multi billion dollar effort (just on the cusp of what it feasible for them). If we can use something more secure, then it's out of their ability. The good part is that often we can increase the difficulty to crack something by an order of magnitude without a high cost to us.
