I agree, this is nonsense. One thing I think
is possible though (but still, not likely) is that they could close down DC Comics and license the characters out to other publishers.
They've already cut DC to the bone, and it has come close to happening before. Once in the 80s DC was in talks to license their characters to Marvel, but it fell through due to anti-trust concerns. And in the 90s when Marvel was going through bankruptcy they considered it too.
Heroes Reborn was actually a pseudo-test run of that.
