Unity has temporarily closed its offices in San Francisco and Austin, Texas and canceled a town hall meeting after receiving death threats. The company made the call as a precaution against possible retribution after it announced a contentious change to its business model this week.
Unity is actually quite a popular engine for a lot of games both 3D and 2D and on multiple different platforms. It’s very popular among indie developers, though there are actually quite a few games from Big publishers that are released under unity as well.
