> Making a profit != profiting.

Thats exactly what it means.

I use linux to write python that I sell for a profit, I profit from these things, and I am happy to support these projects with my profits in return for professionalism I need to make a profit.

If I use them in a personal project I benefit from them not profit, and I certainly don't expect anything more than the benefit of not having to write that code, the rest is up to me.

This is pure entitlement.
