You can't really 'wait them out' unless miners stop doing them.
The swiftest solution would be a PoW upgrade.
The spam has stop about a month ago, then we wonder what happened? But then 'they' are back spamming and clogging the network. We can also speculate as to is behind all of this by asking who are going to benefit from it? Your answer is as good as mine.
You can't stop them from complaining about the fees. However, why are they still in the bitcoin ecosystem and then complain? They totally contradict themselves. LOL. What don't you go to other altcoins that is has a very quick confirmation time? I guess we are all here because bitcoin price is going some places now and the possible profit is really huge in the future for just hodling into it. So I'm not complaining.
