I can relate and have experienced this. The result was that they would end up exporting from a series of Tableau/Looker workspaces, and importing into excel and doing their analysis there. Then continually making enhancement requests on the Tableau/Looker workspaces to get any additional data they need for their excel work. Then of course, the excel document and its multitude of versions would get emailed around until it hit the attachment size limit, or if there were too many version of it to figure out which one was "actionable". We finally figured out what they were doing when the enhancement requests for the reporting workspaces got too bizarre. Insanity.
