While it may well be that other people in the WMF decide some of those issues, the 4
community-elected board members are the only people the community can elect in the WMF
(afaik). We can't even elect the Committee that decides which questions we can ask to
prospective board candidates.
So really this is a bit like the questions asked to US presidential candidates. Many
things are outside their control (eg fall upon Congress or the states), but people still
ask questions about things that matter to them. Similarly, many of those questions matter
to many members in the community. I think board candidates should answer some of them. Not
necessarily all 52, but answering the at least ~10 most popular ones would seem
reasonable. People want to know where candidates stand on those issues.
The board passes an annual resolution for the budget, so I'd say Q47 is relevant. Even
if the board won't be passing a resolution on mobile communications directly, they
still decide the budget that goes towards such issues, and decides the CEO who will pick
the staff that deal with more lower-level issues. After all, the board won't be
passing a resolution on Wikispecies or Wikinews either, yet a question about that made it
in. A common generic question on diversity is asked, but the more relevant, specific
question about diversity concerns in the WMF staff team was omitted. I find it hard to
understand any consistency in the questions picked. It may help me understand if the
relevant Committee explained the process they used to choose.
