This is just an opinion poll by a newspaper.
This is not really voting, or getting involved in politics, its just picking a yes or no to a question posed by a newspaper, though I can see the hypocrisy of JWs who participate in the poll to a small extent, since JWs are not to even have an opinion on political issues.
Lots of newspapers run these polls all the time. They're not scientific and they aren't used to dictate policy. I don't see the advantage of organizing the "world apostate movement" to all "vote" opposite of what the JWs want, unless you just want to overload the server of the newspaper.
edited to add: This issue isn't just about JWs, it involves other churches and non-profit groups. If this poll were influential in changing policy, would we be willing to possibly hurt other non-profits just to spite the WTS?
