This is better than blanket liability for unpaid maintainers, but it's unclear how it relates to OSS activities not "on the market" per se but nonetheless connected to the larger software market. Two examples come to mind: donations to OSS maintainers, and OSS maintainers who provide consulting services instead of selling software. The former is arguably covered by donations not being "sales," but some projects/groups do provide invoices (with no particular obligations) to make donations fit into the sale-shaped financial slot that most companies understand.
