> I disagree that builders “owe” anyone anything
I disagree, but I think "owe" carries too much of a negative connotation. Through your project you enter both a relationship with yourself, having taken on a commitment to achieve what got you interested in starting your project in the first place, and the community (who also could be nobody but yourself) you want to benefit from your project, who want to rely on your project to some degree.
These relationships lead to obligations, few, if any, of them being legal or moral ones. Instead they are obligations put onto you by your own interests. You do not observe them because e.g. your project's community demands them (who, I'd like to point out again at this specific point, may still be nobody but yourself!), but because they are important to you. What is important to you can and will change, of course.
> I strongly disagree with goal of as much profit “as possible”.
TBH, I consider the "within the rules they think should be followed" part essential to the statement.
> obligation for maximal profits - something that I personally hold responsible for all the mass enshittification going on these days.
I'm not sure, but I don't think that's the case, sad enough, IMO the reason is to be found a bit to the opposite:
As a group, the people we're overall aligned with in our values (on this issue), having found fulfilling success in goals way less influential than money.
