What comes to mind to me is the concept of "business ethics". Decisions such as this ought to be made before doing business. A company decides "We won't profit from doing business with (whatever) domains" when fashioning their business model, before startup.
Sorry to disagree rather strongly that this decision isn't a gutsy one at all. Similar versions of this ex-post facto virtue will likely continue to crop up in the business. For a long time domain parking firms accepted famous trademark typos, putting not only money into their own pockets but into the pockets of the those who trade off other company's famous marks, such as Disney. Then, eventually - likely when some lawyer squared up the issue and their spine firmly enough - parking companies started to back away from the practice. Was that virtue? Guts? Good business sense?
Interpret it whatever way you will. I have no praise for it unless they also disgorge all past profits from the practice of trafficking in such domains. Disgorge the past profits and then I might begin to see the emergence of some form of corporate soul, something praisewothy, for the company.
Think that will happen? That would take something like - but more than - guts. No guts here. Just repositioning.
