how is it? maybe not directly, but you do indirectly.

There's always this expectation to get something back, both in the open source world, as in the v4v movement, and in any other thing humans do.

not our fault, we have been trained really well to believe this way

Open source product is a marketing tool

I'm not doing open source for profit. I'm doing open source because I believe in the ethos (and I think that copyright laws are a stupid, out-of-date idea), but I do it as a part of my for-profit venture with the belief that the open source part will bring more attention and customers to the for-profit side of things. 
__Open source is the marketing tool for the business.
The business is the funding tool for open source.
The goal of both is to create or add value.__
In theory, they should start reinforcing each other in time.
