Large fines like these, even if the facts are clear, do not support competition and seem anti-consumer and anti-innovation. Either the fines should be smaller or the laws changed to better balance what concretely happened: a poaching of a key employee that led to the development of a big product.
That being said, Facebook doesn't really seem to have its R&D figured out. It's poisoned by bad leadership. Palmer Luckey managed to disgrace himself in public opinion in a way that seems hostile to recruiting the kind of progressive, free-thinking talent that makes up most R&D teams. John Carmack, besides his political leanings, speaks derisively of "Hollywood people" (Oculus users) and came out of this lawsuit looking like a real jerk chasing a huge check at any cost. At the end of the day, he betrayed a video game company.
Mark Zuckerberg has a lot of leadership faults disguised behind an amateurish ownership structure that puts him outside of public accountability. Despite its huge head start, Oculus is seriously threatened by HTC, Sony, Google and Samsung. Paper and Facebook payments didn't really go anywhere. Though Instagram and WhatsApp seem to be good acquisitions, even at their extraordinary prices, a broken clock can still be right twice a day. And it doesn't really take leadership to spend huge amounts of money on acquisitions—that's the easy way out. Outside of Facebook, his New Jersey schools efforts were not well regarded. Will his $3 billion commitment to a SF Biohub be marred by similar issues? I'm just nervous is all.
I think market sentiment will catch up with this ruling. Eventually someone's going to ask if he's the right guy to be in charge of Facebook. The public investor may never actually have the power to do something about it.
