Sadly, Rob and Mike have been locking their blog down, editing comments to remove criticism, and insisting that in posts entirely about math that the math is not what matters. Access to the LinkedIn group they sell is being locked down when it's used to make polite discussions of how to respond to ethical problems with vendors, and commenting on their blog and linkedingroup, for which they charge hundreds of dollars to access, has been shut off where people politely disagree. They suggest that they are merely removing rudeness, but what they remove isn't rude, and they're leaving significant accusations in place while disallowing response. This community is gated to exclude people who politely point out errors in the math.
