While I do think many media sources have an obvious self-interested bias against Facebook, I think Luckey is biased himself in how he portrays this affair in his tweets. He talks about how the press covered the filing of the lawsuit, but neglects to mention that it was originally filed in 2015, and has been through numerous twists and turns since, being dismissed, reinstated upon appeal, etc. before finally reaching a jury trial.[1]
Coverage in general has declined as the years have gone by, and this latest trial garnered little attention when it started. It wasn't as if there was minute-by-minute reporting that went dark as soon as the verdict came in. Yes, a loss for Oculus would have been an interesting story, and would have been reported on, but the reality is that Oculus and VR are simply not the zeigeisty topics they were in 2015, or even 2017, and so a "Goliath beats David after six year legal slog" story was never likely to be make headlines.
As someone who spent years fighting against a meritless suit, Luckey is entitled to feel aggrieved, and to wish that its end would be as big news as its beginning. But objectively its easy to see why it wasn't, without necessarily ascribing it to an industry-wide conspiracy of silence.
