At first I agreed with you in that my spouse had a negative response to me referring to a particular person, method, place or thing as “famous” when she was not aware of the person. I’ve learned to omit it or say “well known in some circles” or the like.
On the other hand, maybe these phrases like “simply” or “obviously”are less-than-consciously used on the part of the speaker/writer to acknowledge that this reference may already be known to the listener/reader. In that it reminds me of various England-Englishisms that mean the opposite of their plain definitions.
