Sure - working spreads becomes a much harder task with the presence of someone who will often take one of your sides and the next couple of ticks in a few seconds. As bobltrade72 points out, spreaders are likely to decline in numbers.
Continuing with the evolution theme however, this is probably not too bad a thing for those who hang around. As the number of arbitrageurs diminish, the scope for attractive spreading should in theory re-emerge, and could become lucrative in spite of the Flipper. In fact, given that the Flipper (to my knowledge) does not take all spread related products on at the same time, someone who is ready to react to his large trades - or maybe an algorithm - can get into spreads at particularly attractive levels. I strongly believe that purely seeing the Flipper as hindrance to successful trading is wrong and defeatist.
I also think that the Flipper - however clever and smart he is - can be defeated at his own game. e.g. around Aug 2nd last year, it appeared he was forced into particularly painful stoplosses. Admittedly however, there are very few players with the size to take him on...
