I believe the affinity of social media users to cast judgement is a huge factor as well, worse on those that actually do reflect a lot. Although it is perceived vastly more strongly that it is often meant since individual voices overlap. Still it furthers the assumption that many are very judgmental. With that a strongly regulated social media place can be just as hostile as the most vulgar forum you can find. By experience, it can often be even worse. Nit picking is a form of communication as well, perhaps often chosen because users want to share something difficult to do on the medium. That said, nit picking often doesn't carry hostility. Especially on tech platforms it is just meant as a contribution. Maybe there are carry over effects and miscommunication.
