Many people have come to Meta to vote and comment on the proposed changes to the license. However most people coming from other sites don't have enough reputation to down vote answers. This completely skews the votes and could give an incorrect perception of the community's views.
According to the help center:
Voting is different on meta.
Like normal Stack Exchange sites, Meta allows members to vote on questions and answers. For most posts, votes reflect the perceived usefulness: well-written, well-reasoned, well-researched posts tend to get more attention and more upvotes. Highly-voted and frequently-linked posts may become part of the community-curated FAQ or codified as part of the site’s Help pages.
Unlike normal Stack Exchange sites, Meta invites the community to discuss, debate and propose changes to the way the community itself behaves, as well as how the software itself works. On posts tagged feature-request, voting indicates agreement or disagreement with the proposed change rather than just the quality or usefulness of the post itself.
However unlike every other Meta site on the network, on meta.SE users gain and lose reputation through votes. So down voting costs you reputation and votes on your questions and answers affect your reputation. Hence people will be less likely to down vote answers and people will be less likely to post questions and answers if they will get down votes which might affect their privileges. Especially since the majority of users will have very low reputation here.
An example is this very question. My privileges on meta.SE should not be changed by votes which show people's agreement or disagreement with the question. And we should be able to post suggestions and vote on questions and answers to show our agreement and disagreement without having affecting our privileges. If voting on meta is supposed to be different then the reputation and voting system should also be different to other SE sites.
I would suggest making the reputation on meta.SE the same as your highest reputation from the other SE sites you're a member of. Then have no reputation changes on meta.SE. I do not think that simply lowering the bar for down voting is correct. Reputation change and privilege change will affect voting and participation behaviour, skewing voting towards up votes only and acting as a barrier to participation.
