> 4.5B out of 17.4B is 25.8% of total revenue

And 25.8% is "less than 26%", as I said.

> What business are you in that 25% of revenue is not essential?

Lots of biz have 30% variations in revenue. In fact, it wasn't so long ago that MS' revenue was 30% less that it is today. It was even less long ago that Google's revenue was 50% less than it is today.

If that revenue was essential, neither company would be alive today.

Yes, both are happier with that revenue, but it wouldn't kill them to lose it.
