Not really. The real reason is that Oracle has done a reasonably good job of continuing the development of the Open Source project. You can certainly argue about what things they should have focused on (the MariaDB community has done that, mostly arguing there should be more engines), but Oracle has done nothing to damage the project, and a lot of good in it (serious improvements to the main engine, InnoDB).
If MariaDB hadn't been there, and as competitive as it was, I doubt Oracle would have played so nicely with MySQL.
Oracle has one goal, and that is to make money. They've realised due to the competitive pressure in this case that they can't abandon the community and go straight into value extraction mode.
InnoDB was owned by Oracle since 2005. I don't recall seeing any complaints about that at the time. In 2010, when Oracle bought Sun, then there were complaints from the MySQL team. But not complaints when Sun bought MySQL. Honestly, most people had been using InnoDB as their main MySQL engine for the previous 5 years already but there was no whinging from the MySQL team about that (that I recall).
It's all pretty arbitrary in my opinion -- if Monty and company hadn't whined so much when Oracle bought Sun, I doubt there would have been a fork.
Anyway... it never bothered me one way or the other.
