Back in early 2010, Facebook's platform was overrun with game spam due to companies like Zynga. And while it knew it was going to hurt developers, it would benefit users and Facebook in the long term, and so Facebook massively cut down on game spam and virality for those game developers, leading to massive contractions in values, and lots of sell-offs, and startup failures in the Facebook gaming space. But here we are 10 years later, and Facebook is still thriving, so it was clearly the right move.
