You are not surrendering anything there. You made a choice, a choice to trust the restaurant to serve you food in an ambiance in exchange for valuta (money).
You get fed. You get entertained (or at the very least, distracted from mundane routine). You might enjoy it, or not.
If I put on a green jersey, I'm not surrendering my freedom to put on my red jersey... I just made a choice. (no, don't put on both jerseys)
Yes. You're making my point for me. Free software users made a free choice to trust free software developers (as long as those are distinct groups which shouldn't be so clear cut).
It's either you do everything yourself or you trust others. You can choose who you trust, but you can't keep your freedom on how to do something when you delegate on someone else to do it.
You're freely giving away your freedom to someone else in that particular task. And then your freedom to do it transforms on your freedom to choose who to have to do it for you.
You're trusting whoever made your green jersey to use no asbestos, not too radioactive materials, not to use slave labour, etc. You would be sure of that if you made your jersey yourself,
and you could have if you had your own sheep, but you choose not to grow your sheep, or not to pull their wool, or not to made your jersey. Every decision you takes forecloses other decisions
and removes degrees of freedom, but you're no less free because of taking decisions.
So free software gives more options to developers than non developers, but that does not mean that it doesn't give any freedom to non developers. They have the freedom to choose what free software to use
and who to have it made or adapted. They have the freedom to choose how to use it (freedom 0), they have the freedom to give it to their neighbour (freedom 2),
and they have the freedom to learn from it and become developers to help themselves or others if they want (1,4).
I understand that free software is easier to understand for developers than for non developers (users are we all). But that's an information issue, not a freedom issue.
