I just googled and I don't think that's true, at least not the origin of the story. The original story came from The Columbian and Erik Gunderson:
https://www.columbian.com/news/2015/jun/25/sources-aldridge-tells-blazers-he-wont-be-back/
he was claiming sources were telling him Aldridge was gone, and I'm sure Dave wasn't the source. He also had sources predicting that Portland was going to trade their 1st round pick right after the draft, so it sure looks like Gunderson's sources were good since Aldridge left and Portland traded their pick
Dave may very well hate Olshey, just like a lot of the Portland media and blog-o-sphere does.
I seem to recall that Aldridge himself implied that his re-signing intentions had bee exaggerated by Portland's FO but maybe I have it wrong, as I said
