“Pay seven figures a year to buy a corporate subscription to my newsletter and I’ll say nice things about your company, and when the press needs a quote, I’ll be there to puff you up. Or, don’t buy a subscription and I will bash you relentlessly.”
This is not a new game. "No one gets fired for buying IBM" was born, then later became "No one gets fired for buying Microsoft" on the back of "industry journals" that were more or less the dead-tree version of the rackets Fake Steve is describing. None of this is new. This, more or less, is the history of subscription trade journals in every industry for the last 100 years.
Model is thus: Subscribe to our journal, we'll ply you for survey responses/advertising. Fail to pay? You won't get reviewed or if so, it won't be flattering. Advertise? You'll be reviewed, and positively so. Oh, and we'll charge you for the report born of the analysis of the survey data you gave us. Repeat for all major players in a niche field. Welcome to industry publishing.
