That discussion concluded essentially the same thing I said: that both the OSI and the FSF have essentially the same conditions and that "merely having the source available is not enough to meet what the OSD defines as open source" (sic).

Don’t police perfectly innocent and common use of language please.

Using "open source" for all kinds of source, regardless of how restrictive its license is, is definitely not a common use of the term.

People aren't gonna start using "open source" like that just because a few people find it more convenient for the marketing of their projects. To me it sounds like they are the ones policing to push for a particular language standard against what people commonly use, which is what makes language prescriptive, instead of descriptive.
