This is a bit different to the Reader scenario. They're not shutting down Google Groups, they've shut down one particular group, without explanation. I think the symfony community would be happy if we could just get to the data to move.
It's not: Google doesn't care about its users in both cases.
I wouldn't say that they don't care. They certainly appear not to prioritise the customer, who when selling services should always be the single most important priority.
