Silly argument with prior evidence to suggest incorrect
Back in 2004, the X Windows implementation used by Linux was XFree86, the XFree86 project changed the license and this upset people in the community. The code was forked and taken on by a foundation called X.org under the previous license conditions, within about 6 months all the major distro's had migrated to back X.org instead of XFree86, they still use X.org now, XFree86 is pretty much non-existent.
In order to migrate from MySQL to a fork, it just needs the support of the major distro's on Linux and a tiny bit of marketing for the other platforms, given that none of the distro's will want to be particularly reliant on Oracle (least of all RedHat), you can be fairly sure that they will get together with the community to back a fork as soon as Oracle takes control.
Biting the hand that feeds IT
