There might be more to it than that. Writing a piece is SA by itself is not enough to crash a stock. The quick rise made the price precarious as many investors rightly take profits but I believe there was also trading aimed at bringing the stock down. Would a pharmacist have the wherewithal to do this trading or was he part of a larger organization? If Ascent Capital were a legit business, would he risk destroying it? Could the Linkedin account and the AC website have been created for just this occasion? Why destroy them if not to hide something?
The story is fishy:
Going long without reading the SEC filings, reading the filings on having a gain in the stock, having an epiphany and doing a 180 warning all who would listen out of the goodness of his heart. I always mistrust those who do things for me, not themselves. It's just out of character.
