The EU parliament is the only aspect that is partially on the side of the people. But on the other end there's the EU Commission, the council of ministers and the entire corrupt EU bureaucracy that is beyond any form of oversight.
Parliament is the least powerful element of the EU, and any positive news that reaches HN from the EU is usually about parliament managing to pull off a rare victory over all of those other forces. (For instance Net Neutrality or defeating ACTA.)
And this only after massive popular lobbying of said parliament. EU parliament certainly isn't "firmly" on our side, but since their the only part of the EU that is actually democratically elected we can occasionally get a small majority to interrupt lining their pockets and take a stand.
The EU itself is a backdoor for treaties like TTIP and CETA. Without it, such treaties would have to go through the democratic processes of sovereign nations, which, although far from perfect, are most certainly more transparent and democratic than the EU. (At least, that was the case until the EU started including blatantly corrupt nations.)
If we can stop this, it's despite the EU, certainly not because of it.
