If you recognize something as wrong in principle when taken to the extreme shouldn't you also regard milder instances to be wrong as well? "Well sure, if you steal $1M that's obviously immoral but that guy only stole $100."

Of course in this case I recognize that there's quite a bit of uncertainty over how exactly the intent and representation of RSUs ought to be interpreted. I had always seen them as akin to a signing bonus but it's clear now that many people don't share that perspective.
