The biggest problem with the media's complete abandoment of all principle in continuing to treat Twitter as a high integrity platform is the message it reflects to all other social media platforms : your users are captives. They can't leave. Once you have enough of a network effect going, no amount of disreputable behaviour or abuse is too much.
In my view, it's becoming imperative that Twitter (and now Reddit) actually fail to save the internet. (You could put Facebook there too but I think these days it's actually lately been more benign than the other two).
