What makes you think down/upvotes are related to political beliefs? It could be that people think you are making a good/bullshit argument, regardless of their political inclination.
1. The poll was framed in a way that did not make my opinion
available.
2. Nobody else had expressed my position so I thought that it
was uncommon.
3. I assumed the poll was meant to try to force Dropbox to drop
her from the board.
4. I expressed a position that wasn't that political but that
I knew would anger or confuse political witchhunters.
5. It is quite common for people to downvote information that
does not agree with their ethical aesthetics.
I couldn't possibly speculate on who the best people to make or maintain political links are, but my speculation is that the more connected to government you are the more you will be able to affect policies affecting the tech industry.
I said no such thing. Seems like you're the confused one now.
Have you read the newspapers lately from ANY part of the world? Does it still need to be explained why, in general, being cosy with the politicos is usually a good thing?
