I've read various stories over the years about Oracle extremely aggressively pushing high bills because they think you're using the "free" version of MySQL or VirtualBox in a way that you're supposed to pay for it. I'd be very wary running anything "free" from Oracle (as in: I wouldn't).

I had the same worries, but my Oracle account literally can't access any paid services. In fact, it's so bad that when your trial expires (you get some tryout credit) I couldn't even pay to continue operating if I wanted to, the resources had to be recreated from scratch!
