That’s much more than I would have expected. ~3.5% is a significant operating expense. Not sure why it should be higher. Most companies don’t spend that much on R&D for example (tech companies are exceptional in this regard).
I’d argue it’s sufficient I if the problem of moderating content was a non-issue. However the article points out the problematic nature of the way content moderation currently works. Given that content moderation is core to their business, I’d expect the percentage spend to be >5%. By comparison they spend about 2x on Oculus.
