That is certainly not universally true. It is common, but not universally true.

And we should assume that the authors were NOT aware of real ecosystem implications of licenses - because nobody understands these in detail. I've been trying to understand them since the mid 1990s when I started contributing in a BSD environment, and I won't say that I properly understand them. I understand parts of them, but I don't understand all of them.
