Let's say there are 10 companies that need 1 GB of RAM each in a life-or-death scenario. They would be willing to pay $100,000,000 per GB to get 1 GB of RAM.
At the same time, there are 90 more companies that need 1 GB of RAM each to make certain quarterly targets. They are willing to pay $10,000 per GB to get 1 GB of RAM.
If you make 9 GB of RAM, you can sell it for $900,000,000. If you make 99 GB of RAM, you can only sell it for $990,000, because the 10 life-or-death companies only need to bid high enough to push out a quarterly-target company.
It's a bit of a contrived example, but it shows you how restricting supply can boost total revenue if there is a segment of the market that has inelastic demand. (this is why medicine pricing has to be regulated - in the medical industry, there are lots of inelastic demand scenarios that can lead to predatory pricing)
