Why it won't happen again? Because first one surprised professional lobbyists.
Now there is no more surprise and people involved on the grass root side have all realized when reading the proposed EU constitution that it was hugely worsening the situation and that future was near hopeless so they're no longer putting a huge fight.
You can't reasonably fight as grass root against more than one IP idiotic directive per year.
AFAIK all swedish euro-parlamentarians voted no on IPRED2. I do not think it is a coincidence that they are well aware that Piratpartiet will be running in 2009. This will be an issue and they prefer not to loose votes on what (from their perspective) is a marginal issue.
And thanks for this diary. A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!
You may be right about the limited stamina of the grassroots, the Surveillance Directive passed pretty much without a fight after the battle against the Software Patents Directive was won.
I don't think the amendments of the EP made IPRED2 worse, by the way. They made it less bad. But the best thing would be not to have the Directive in the first place.
