I have many mixed feelings about this post.

I think I understand where you're coming from and how you want those who create great things to be well supported by the community here, but I also hear a bit of the "Utopist" thinking you, said you're not doing. It's possibly I'm misunderstanding you (and also possible the language differences play a part in that), but it kind of seems like you have an entitlement mentality where everyone should have access to value regardless of what they contribute. To me, that simply does not work.

I have some more thoughts on that here and here. Expectations are powerful, and if we don't control them properly they can make us angry, sad, frustrated, etc.

I think @arcange is a fantastic person who can charge whatever he needs to in order to be motivated to provide the service he provides. Others may disagree and do something similar for cheaper. Or maybe it will just go away and people will use other options such as MongoDB. The point is, the markets will determine how to price things because no other system out there can without threats of force (i.e. government). I'm okay with that. I also think those who provide value should be rewarded. Those who just want to take value without providing anything, well, they are what I consider a moocher. They aren't helpful.

I think you're asking a lot of good questions and they seem to come down to a core question:

How do you define value itself?

Many people get confused by this. To me, financial value is determined in the moment of transaction. It's subjective. Just because SteemSQL was previously "free" doesn't mean it wasn't valued. People don't often pay for free things. I think SteemSQL is valuable and I, personally, will pay something to use it. I only run a half dozen queries a month currently, so I'd personally prefer to see a pay-per-use model. Or, at the very least, cut off the people who are over using it. Give everyone a unique login and those who are using it too much have to pay. The rest, well, they aren't the ones driving up the costs of the infrastructure.
