Ah! I get that. +1! In my circle, that use of the word “taste” is almost always a negative, as in “Reg made a tasteless joke” but certainly it can be used positively, as in, “Reg’s commentary on admiring Steve but not deifying him was in good taste even if I don’t agree with it.”

I was mixed up by the comparison to Bill Gates, who I don’t see as being tasteless in speech but whose company I used to view as being tasteless in design.

But you are absolutely using the word appropriately, whether I agree or disagree with the proposition that Mr. Stallman’s commentary on Steve Jobs was tasteless.
