It's not a case of hoping no one exploits the vulnerability. ECC will almost certainly be broken at some point in the future, and any coins protected by it will definitely eventually be stolen. We will absolutely move to a new algorithm, but it should not be the decision of the majority to lock coins which we do not own with no say from the true owner. I would much rather those coins are stolen than we set a precedent that the community can decide to lock your coins and there is nothing you can do about it.
Vulnerability in protocol is a very different thing than "locking other people's coins". Lets take OP codes that were disabled/removed from protocol. They had vulnerabilities and if anyone had any coins locked by an OP code like OP_CAT their coins would have been locked because such output can not be spent.
Or for example if you had any coins that were locked with a script like the following (pubkey script) they are unspendable now that BIP-147 is active because "majority decided".
OP_1 OP_0 OP_0 OP_CheckMultiSigVerify OP_DUP OPHASH160 <hash> OP_EqualVerify OP_CheckSig
You see in bitcoin the majority has been making this kind of decisions for a very long time and it won't be any different for ECC in the far away future either.
