As someone who got caught up in it both times, 11th State had two issues. The first (and main) issue was that they had a nurse practitioner signing recommendations. DOH decided they didn't like that suddenly, and anyone who had an application in with an NP signature was rejected (both me and my wife in this instance).
Next, once they got an actual physician in, the DOH tried to say that 11th State wasn't a "licensed healthcare facility". In this instance, there was never an interruption of business, and I assume that 11th State paid whatever extortion the DOH was after to get licensed.
In no case that I'm aware of was there any retroactive card-yanking.
As for Slater, I guess they're banking on there being enough people who were paying black market prices before to keep them going. It honestly wouldn't have bothered me except for Joel's bullshit "we're about compassion" speech vis a vis prices.
