Forward PEs are obviously just guesses, and not even attributed. 

PEs based on latest actual earnings are facts (at least somewhat factual--there is of course the question of GAAP vs non-GAAP.)  

Publishing forward PEs tends to encourage speculation  by inexperienced or careless "investors" who may take them as reliable, or even as SA's own investing advice--not something I should think that SA would want to do.
