You present a solid, clear argument Ken. Thanks for the show. My understanding of it is that they (RMS &amp; co) didn't fully appreciate the bug until people started using the term 'free', ie it's a runtime bug. And once it's entered common usage it's hard, if not almost impossible, to alter that usage. For myself, I can live with the ambiguity by minding context and saying "free and open source software" when there's likely to be ambiguity.
