Van Sciver is legitimately insane. He's damn near chased himself out of the industry because of it despite being a talented artist. He's burned bridges and has big axes to grind as well. Gonna need a way better source than him for this info. It wouldn't shock me if his "source" exists only inside his head.
The thing about this whole "DC is going to shut down!!!" stuff is no one reputable is reporting on it. It's all marginal characters and clickbait sites. Rich Johnston, who is a questionable person but undoubtedly the top rumor monger in the industry, hasn't so much as made a peep about it and you know if he'd heard anything about it he'd be wallowing in it like a pig in shirt. No one with any legitimate connections to the industry seems to be acknowledging it much, if at all. I'm not saying it's impossible, but so far the information is coming from areas that are lacking credibility to say the least.
