PyDev is now open source.

PyDev was made available as both free and paid versions (PyDev & PyDev extensions respectively). I believe the paid version costed $40 USD, which in my opinion is NOT worth a dime at all considering how better and functional (yet free) Netbeans's Python support is.

Netbeans and the proposed Eclipse's own Python IDE must have forced the PyDev drop the commercial tag. Another reason why I love Open Source softwares.
