I see where you want to go with that, but I'm not sure you made the argument you're trying to make.
Ballmer didn't 'make money from extracting rents and screw everything else up'.
Ballmer entrenched and expanded MS core products i.e. Office to the Cloud and along with that massively expanded revenues, which continue to this day, long after his departure, with no signs of slowing down.
He completely screwed up Search and Mobile, but those were risky new things, that's to be expected. Frankly he should have had 1 of 2 ...
But he also established XBox and Cloud; the former is a very successful play into a very difficult space (though maybe not as nice in terms of profits) - remember, Google just completely failed at this. The later, is now a hugely successful and growing business, and frankly, over the long haul has a shot at actually going toe-to-toe with Amazon.
Microsoft has 10's of thousands of sales people and direct access to every single CTO in the world if companies with > 1000 emoloyees. Much the same way they are going to stomp Slack, they have that kind of advantage (though not the same leverage) against AWS. Point being - he started a massive business.
Azure now has revenues of more than Windows did when Ballmer started, and it's growing by 40% YoY.
So yes 'revenue' is not the 'whole story' if someone is bilking a cache cow and running everything else into the ground ... but that's now what happened.
Ballmer 'grew and entrenched the cash cows' and made some other huge bets, some of them working out to the point where they are now also, big growing foundational aspects of the business.
'The Market' took a long time to recognize this, but all the historical sales numbers are there for everyone to see.
I believe that once Analysts realized that 1) Windows and Office is 'here to stay' and 2) due to AWS, Azure is going to be huge ... that they revised their view on MSFT from a 'old company' to a 'well run growth company'.
Satya seems great and has made some good moves, but nothing of the magnitude that Ballmer did. At least not yet.
