I still have problems with the sponsoring of the event. If Gaggle, M$ et al are sponsoring it, I might not be interested. I know there's a couple of people in the @fosdem organization that feel that way as well, but they're a minority. AFAIK the issue is to be able to spend time to find more smaller sponsors rather than a small bunch of large sponsors. So the more interested people, the more chances to avoid surveillance capitalist sponsors.
