Are there really any significant acquisitions happening just for some database? I don't think this happens unless the data is absolutely massive and very unique.
My biggest problem with Mozilla is that I pay them a monthly donation and it is real hard to cancel it. They had no problem accepting it. It's just a bit too nasty.
I'd add that there are now so many bootcamp candidates that want a J-O-B and have a passing interest in computers that just filtering them out gets old. The only realistic option for a small team is to reject bootcamp candidates from the get go. You will of course have a few exceptions, but good luck finding them.
A comp sci degree really is a much better filter for junior devs.
