Not to mention this was known as a possibility for months...Mt.Gox told us this was a possible issue quite a bit ago.

Can anybody do something to fight against this ATTACK?

This is no attack on bitcoin. This is a fairly logical and predictable consequence of operating financial service companies, which exchanges are.
The bitcoin aspect is still free as ever, the EURO part is not, it is regulated, and thats perfectly fine with me.

For those, who like me, think bitcoin should get a chance to become a currency, an actual trade facilitator, rather than a casino chip thats useless outside the casinos you call exchanges and bitcoinica, this is excellent news.  If you want bitcoins, start selling goods or services for bitcoins. If you want to get rid of your bitcoins, buy good or services with them. If you have no interest in either, then bitcoin isnt for you.

Gotta agree here.  This has little to do with Bitcoin per se and everything to do with offering financial services without the appropriate licences.  You accept and hold user deposits or transmit funds between users and you're going to need a licence - even if you're accepting those funds so people can trade Beanie Babies.  People have been bringing this issue up for months and the response of the exchanges has tended to be that they don't need a licence because...Bitcoins.  

Once there was a ruling in respect of one exchange in Europe it was almost inevitable that other banks would make decisions about their exchange clients which are consistent with that ruling.  It's highly possible that they've been waiting for the battle to be fought in France so they didn't have to go through the process of seeking determinations themselves about the nature of the business their exchange clients are operating.  But even if they weren't especially waiting for this ruling, such determinations get quickly circulated within industries as a matter of routine and legal departments specifically look into whether those rulings are relevant to operations of their own employer.

I hope that before anyone opens any more exchanges they'll fully investigate the financial regulations they'll need to comply with and the cost of doing so.  Not all markets are going to prove viable for all players.  The cost of compliance with financial regulations may well mean that some markets aren't going to be viable for young exchanges (and all of the exchanges are young).  Exchanges need to determine that in advance instead of just opening in new markets and hoping for the best.

Of course. Bitcoins do not need license! I have predicted 4-5 months ago this is exactly what will happen. This is inevitable and this is good for bitcoins. Very good!

eazy now. this is not an attack.

The best thing that we can do is to use our bitcoins as much as possible and exchange it for fiat as little as possible.

The answer is part of your question.
It is not simple and it is very expensive. In general, if you do it you make bitcoin part of the fiat world. This has to be avoided!
