It’s being reported on by dozens and dozens of sources. I doubt that they’re all fake.
The report of separation of Steve Bannon from the Trump World might not be fake, but a lot of the circumstances are sure to be either misreported, or grossly overstated.

Even Anthony Scaramucci had a purpose, no matter that it was short-term. His purpose was simply served much more quickly.
