Not sure what kind of organizations you have seen, but Metabase/Redash would max cover 20-30% of the use and Tableau 80%. It depends a lot on the type of data you have, but anything beyond sql will not work with Metabase or Redash.
Tableau is awesome, but I believe that most of its features are not used soo often. A simpler tool can provide almost the same or more value than Tableau in some cases. Well, a tool that you don't need to pay expensive licenses for each user makes it more democratic, everyone on the organization can visualize and create new analysis.
I totally agree we need something cheap and simple, but it must have some level of "functional" calculations a la excel. Now if users were exposed a pandas dataframe in Superset or Redash or other, that would be extremely cool and would for some cases be much better than Tableau.
