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.
Mostly PowerBI, plus a little bit of the "operational analytics" movement, which is essentially an anti-dashboarding phenomenon. Example operational analytics tools that aren't dashboards but that can be used serve a similar purpose are Get Census, Hightouch, and Grouparoo.
