The fact that these two groups of people have made mutually incompatible license choices is just the way things are and the fact that they are free to make those choices is a good thing. It's not a reason to object to this work.

That's your assumption; presumably based on the assumption that everyone's like you. Not everyone is willing to modify the software they run, especially when they know that doing violates an agreement that they have made. It's not technically incompatible if, as I say, your primary goal is to ensure that the content is protected in transit and only transiently, and incompletely, in the clear.

This level of protection is, in analogy, like a fence around your garden.  No, it does not keep out the determined -- but those who cross it have to take some trouble, and they know full well that they have crossed it.  And maybe the person they agreed with will find out that the agreement has been broken, too.
