good and working products - thats mean successful project, it profitable when it popular, so of course it is very important
And that should be where the main income from the team will come. A good product will get a lot of popularity and a lot of users and that means if that product can give more money to the developer to continue the next development for the platform.
But it depends on what type of the project it is, because in my opinion a project is very important thing, it is not surely the scam maybe it is true one, as it should be interesting one which can attract people to invest in your product, as everyone wants better quality and guarantee so in any business project has really important and serious intentions.
in my opinion, not the main intention of the project, but most importantly a working team that was able to carry out at least a small successful joint work.
