Not surprised... there have been hints of this on the TrekYards channel on YouTube for a while. Though unless they've had more in the last week and a half since I've checked, they never reported it as being quite this bad off.
For those whom don't know about them, they, two guys, talk about mostly star trek ships in various detail (Klingon, Romulan, Federation, etc, basically any ship on screen) and even interview with the original designers on some of them (Probert, Jefferies, etc...). Mostly canon ships, but also fannon and fan film ones. They *also* comment on anything they've heard in regards to rumors and designs... be it Discovery, STO, fan films, etc...
They have access to a lot of behind the scenes material and some interviews because of the various connections and them being a known element in the community.
And they've reported a lot of the known troubles with Discovery pretty much within days of them happening.
