Why? They seem to be doing things they ought not too. Please explain
What ought they not do?
This is another of many recent cases where courts and governments are changing decades-old rules. Not that it's a bad thing, but it certainly doesn't mean the previous rules were wrong either, for their time.
For example, the past few years has seen courts suddenly decide that FRAND-encumbered patents cannot be used to get an injunction, something which had been possible before then. (There are still judges who disagree with this recent change; to them, patents are patents and should all get the same protection.)

Now there's a big lobbying/lawsuit effort to change license pricing. Obviously for less (you never hear anyone argue that they're not paying enough - grin).
I've mentioned before that Motorola, back when it held most cellular patents, only had two license methods. Neither was a direct cash payment. Either you cross-licensed all your patents with them, or you only bought Motorola equipment and chips. This was not seen as unusual at the time. Nowadays people would howl that it's unfair.
Likewise, the ETSI FRAND contract -- which everyone including Apple has signed -- specifically states that requiring a cross license is a valid FRAND rule for cellular patents. But now governments are rewriting the rules, telling Qualcomm that they can no longer require a cross license, and if there is one, they must give fair value to the other company's patents. Again, this was never a requirement before.
There are at least a half dozen other similar recent changes or change attempts, as seen in the Korean FTC rulings and in Apple's lawsuit. These are not really about what WAS; it's about how they WANT it to be. And they want it to be cheaper so they can make more profit. (No one thinks Apple is going to lower prices if they get a cheaper rate.)

The upshot is that no doubt changes will be made, but it's not really fair to paint Qualcomm as evil when they were doing what was considered pretty normal for decades... and for which companies gladly paid at first.
