It is expensive if you have a lot of people. Paying $2k for a license may be for two or three analysts is a good deal. Compare this to a start up like Looker which costs substantially more to get your foot in the door (last I checked, correct me if I'm wrong.)

IBM has chosen to display "Analytics" as a major piece of their company. Presumably they want investors to think this could generate billions of dollars in revenue yearly. Worst case scenario for me would be IBM to buy Tableau, but clearly for those of us who use it, Tableau is one of the best tools out there for what it does. Will it be able to keep its marketshare 5 years out? Who knows.
