Are you/they planning to add them together against the "stay open" option again too? From what your saying the "open" option would have won already in the previous vote.
Regardless, leaving the community restricted with a vote will lead to less folks caring about the sub over time and eventually it dying off. There's about 175k folks there vs about 400-ish here - this place isn't the answer to putting a quality sub on life support.
Because it happened last time when the poll didn't go as you wanted. I'm sure you understand many having skepticism about this.
