I disagree. Is SAP deceptive just because one popular organization prefers another definition of open source? The OSI did not invent the term "open source". The term "open source" itself should not imply a specific license.

It's not because the OSI prefers, it's because it's the mainstream, generally accepted current definition of the word. I mean, if I sold you a "broascasting system", would you accept something that casts seeds out?

It doesn't. It implies a set of conditions they have to meet. BSD, MIT, GPL, Apache, WTFPL, are all different Open Source licenses.
Actually, Eric S Raymond, one of the founders of OSI, was also one of the people credited with coining the term "open source" at a meeting discussing Netscape releasing source code.
