So "A Player" is on a pointless project not providing value to the company gets axed. The value to the company is losing with that "A Player" is nothing because the project they're working on is pointless.
These companies could take a more twitter like "print out your code" or global stack ranking to lay people off but i don't think it dodge the problem people describe. The "A Player" could still be mad that all their coworkers got fired and/or the "pointless project" they enjoyed working on got axed and still leave. You just get the add cost, drama, and blow-back (see twitter) that a performance based firing would entail and probably open yourself up to lawsuits (IANAL) if you don't have an adequate paper trail for those performance based filings.
