Well, what are the downsides of lock-in - why do you want to avoid it?
Loss of control, mostly.  Open source does mitigate that some.  You
still have high switching costs if you integrate, in the *SQL example,
a lot of some vendor's specific extensions. However, you're not forced
into upgrading, or paying suddenly much higher licensing fees, or that
sort of thing.  So while there is still some risk, it's more
manageable, and you have more control over your own destiny.
