A lot of what this guy says does make sense. But he has his critics:
Tom DeWeese of the American Policy Center branded Keiser as "a new kind of terrorist"[29] - specifically referring to Karmabanque, a project instigated by Keiser and his partner Stacy Herbert to de-stabilize the share-price of certain companies susceptible to boycott by encouraging pressure-groups to use short-selling strategies.
The Guardian newspaper, in an editorial titled "Mad Max," described Keiser's Karmabanque hedge fund as "fantastical scheme" and accused him of trying to exist "beyond the normal forces and controls of society."[30]
Keiser drew criticism at the 2000 ShowBiz Expo in Las Vegas when he said of media content that "Everything is inescapably going to a price point called free." In response Kevin Tsujihara, exec V.P. of New Media at Warner Bros., commented that "Piracy.com" will be the victor if superior content is available on sites supported by advertisements.[31]
Professor of Economics Catherine Lubochinsky in a debate involving Keiser on September 18, 2007, criticized Keiser's predictions that British house-prices would drop by double-digits and that the entire banking system would collapse. In a programme discussing the failure of the Northern Rock Lubochinsky responded that the Keiser's first prediction was implausible[32][unreliable source?] because "people still need to live somewhere" and simply dismissed the latter.
In 2005 Steven Milloy, the "Junk Science" commentator demanded that Keiser be removed from the panel of the Triple Bottom Line Investing conference, where he was scheduled to appear. Milloy accused Keiser of making threats[33] against his organization and petitioned[34] sponsors Calvert Investments and KLD Research & Analytics to withdraw from the project. Robert Rubenstein founder of conference organiser Brooklyn Bridge stated that Keiser's comments “do not constitute a threat to person or property and are not related to the conference or the content that will be presented there”.
Referring to Keiser's Karmabanque project a RyanAir spokeswoman said "Since they put Ryanair on their list, our share price has gone up by 10 per cent. We are always delighted to be part of a list which includes Coca-Cola, Starbucks and Wal-Mart."[35], however on the same day The Hindu published an article in which Howard Millar, Ryanair deputy chief executive admitted that his company may be vulnerable to environmental pressure groups: "I am concerned that there is a continuing media campaign and the concern is that people might say 'maybe I will not fly on holiday and maybe I will make a different choice'."[36]
