Because several of the key members have moved (or will move) out of Somerville, leaving not enough to sustain the group. Unfortunately, nobody was able to run a successful membership drive (they say they put a lot of effort into trying to get new members, and while it's true that people did work hard and try, I think the effort was not well-used and we could most definitely fatten the group up if given the chance, but it's too late now) so the group is effectively disbanding into news one at the new locations of the more active members.

The coop doesn't work with produce so the CSAs complement it rather than conflict. The problem I had is that I just don't use that much non-fresh food (and my roomie likes to buy things like paper products at a warehouse club), and the particular items I do use and wanted to buy weren't necessarily any cheaper through the coop than at the supermarket.
