In my experience PowerBI seems to have had wide adoption. Not sure if it represents a better value proposition in itself or if MS were just able to integrate it with their other products which are already dominant in corporate environments.

Microsoft made PowerBI a really cheap "would you like fries with that" purchase for enterprise E3 licenses and above, and really undercut Tableau's cost (I recall it's less than half the per user price). So a lot of corporate expense management types came down with "why would we pay for 2 tools that do (mostly) the same thing", and Tableau doesn't get renewed.
