I think this is more confusion around language for something which isn’t quite that simple. The page that quote is from is a summary, not the actual statute, and each agency will have different policies, as well as terms written into contracts for actual procurements. In general, I’ve found literal statements of fact to be uncontroversial (e.g. if you say X.gov uses Y, and anyone who looks at sam.gov can confirm the same), but it gets increasingly more likely to raise challenges the more it looks like a recommendation, especially if it includes superlatives about the product or service. Anyway, if this is remotely relevant, get a lawyer and ask the agency in question since they’ll likely have some nuances.
