It’s time to end the nonsense. OSS is practically always commercial, which means that there are two major types of commercial software: proprietary software and OSS. Terms like “proprietary software” or “closed source” are plausible antonyms of OSS, but “commercial” is absurd as an antonym, and phrases like “commercial or OSS” make no sense.
This has real-world implications. In particular, government acquisitions (including work performed by contractors) must include OSS in their market research and must carefully consider OSS candidates.
