The thing was that when Sarah took part in the EW article to officially announce it,it was already well-known that Buffy was finishing. David Fury also said that they always knew it was a two season pick-up with UPN, just nothing was officially announnced. All season 7 seemed to be about bringing in closure and going back to the beginning. There were many discussions all season about how they would continue the show without Buffy, with plans for a Willow spin-off, or one centered around Dawn or Faith, even a potential slayer school idea. The fans by and large knew that the show was over, that's why there was always so much defensiveness whenever new characters like Dawn's friends in Lessons or the potential slayers got a lot of focus, because fans were worried about them being pushed forward in preparation for the spin-off. So for Alyson to then say that no one on the set had any idea that Bts was ending always struck me as being very disingenuous. Joss actually later came out in response to Alyson's comments to say that it was his responsibility to inform the cast and crew, not Sarah's, and he apologises if anyone felt like they were left in the dark.

But yeah all most fans remembered from that interview was how coldly Alyson painted Sarah, and how she feels horrible for the crew members to have to find out about their jobs ending through a magazine article, even though it didn't seem like there was a lot of truth to that and Nicky Brendon also said at a convention that that's not true and Aly needs to stop saying that
