Oh, and if some free software programmer's view of something *were* biased because, e.g. that something was the product of a competitor of their employer or their employer's corporate allies, that does NOT make them a bad person. Indeed, I would *expect* a person to be biased toward acting in the interests of their employer - that would make them a *good employee*.
Such biases do exist, at various levels of consciousness. That is not to condemn them. However, we should be aware of them, and take care to note affiliations.
