Employee to employee.
Sun really didn't like the MySQL employee contracts, especially the early ones that had some very very employee-friendly and open-source-friendly terms.
And many of us employees in turn really didn't like Sun's contract, even tho they claimed they were bending over backwards to be flexible and accomidating. If that was, in fact, the case, I don't really want to think what they were like before they were so "flexible".
There is a near revolt going on in MySQL staff, and it's still not fully resolved, even tho the merger is now "finalized".
I did, in the end, sign. But at the first sign of them being assholes, the door is unlikely to hit my ass on the way out.
