Oh come on, I'm no fan of Oracle but this is some FUD nonesense..
It's not that all the stuff is bad or that all the 'free' things turn sour, most of the things are technologically sound, but there is just so much lawyering, licensing and IP fighting that takes all the joy out of life. This isn't unique to Oracle, but not even IBM is as passive-agressive as their non-tech people and documents are.
I’m surprised you called it FUD, given the high-profile case against Android (google).
I was about to recommend we try it at my company and gave up as soon as I read “Oracle” in the company name.
Call it FUD if you want but Oracle does have a damaged reputation.
