It is human nature to attribute success to self and failure to outside influences. When you make money as a day-trader, it is due to your knowledge, skill and intuition. When you can't make enough money, it is because of somebody or something. Can it be the evil HFT and the rigid market infrastructure?
There are different ways of making money. One can invest in technology and infrastructure to achieve competitive advantage. Others use human psychology and desire to find somebody to blame in order to promote their own high-frequency ticker plant or equity trading platform.

Yes. It looks like we can end up with a small set of strong pan-European exchanges. I hope it will lead to competitive and efficient market

I think technology can do it. An advanced electronic surveillance system should be responsible for spotting such anomalies, alerting market control and enabling them to take appropriate actions.  The question is whether solutions that are currently available satisfy these requirements
