>but in practice there's strong correlation. It might be for many reasons, but I'd guesstimate 90+% of open source is also non-commercial. Your guesstimate may be right or wrong (also see sibling heavenlyblue comment), but my point was more that those writers I mentioned, do not seem to realize that open source or free software can be sold as well. They seem to confuse FOSS as being *synonymous" with "free as in beer". And even if "90+% of open source is also non-commercial", that can be just because many people do not charge for their open source software. There's no rule that they cannot, though.
