Slashdot reports that Borland is giving JBuilder away on Eclipse now:

"The Register is reporting that Borland has released the base version of JBuilder as open source on Eclipse! Is this just the next company to use open source as part of a marketing tool, akin to Sun, IBM and Oracle's opensource IDE push? Is the future of enterprise IDE open?"

So my question is: What's the revenue model (for Borland) behind this? Too many people look at open source as some sort of good/evil divide - at the end of the day, the more important question is: where the revenue comes from - no revenue, no business...
