Generally speaking, I think people have three choices: One is to pay for what you use and have a direct relationship where you have at least a little influence and stake with the company.
Another is to go with community projects where possible. If they are healthy and well-run, you should be in pretty good shape over the long run that they won't act against your interests. Here I'd look to Debian which has a very strong focus on governance and doing the right thing. (As they define "right thing" and it is well spelled out.)
Finally, do what's convenient and cheap with the realization that you will likely have to come up with a Plan B someday. This is sort of like the undertaker and Don Corleone: Someday, and that day may never come, you're going to have to pay a price and you don't know what that price is going to be.
