I know this question isn't going to change company policy externally, much less internally, but I think it's very important that the community gets a voice in this.
Should Stack Exchange staff be allowed to vote in any of the: community elections, meta Q&A, base site Q&A?
Should Stack Exchange staff get to alter what is shown and not shown in any of the: community elections, meta Q&A, base site Q&A? This can be either by altering what is visible in the question tabs, or by altering user permissions.
Finally, should Stack Exchange staff get to alter pages on a specific Stack Exchange site, thereby altering the rules by which they follow?
Note that all of the questions above assume that not the community nor the moderators have given consent to said actions.
As per request of πάντα ῥεῖ:
One may compare the legitimacy of staff voting in community elections to the US Federal government having a say in state and local elections. This is not something that is wanted by the United States themselves, nor the federal government.
The same analogue follows with Meta Q&A: Why should one person in the US west coast be telling another person in the east coast how to live? That's not a community. That not what Stack Exchange claims to praise.
Altering what is shown is also a big no-no, and the reasons for this should be obvious. Why should some be hard and others silenced? Obviously, that's a be- all end all. On a smaller scale, things like shadow edits have been enacted on posts which don't show up in edit history, once again removing the power of the users.
