I have had the same thing done to me. Full familysearch.com census citations changed to 1900 census, e.g., Find A Grave source reduced to just a number, etc. because it looks "neater". We are supposed to make full sources available for everyone. In fact I have been adding full sources to some profiles that have just a one liner and putting it below and in the explanations I say "Expanded source link". So far no complaints, but neither do these people seem to pay attention to the profile to fill it in themselves.
