Fully agree, nobody knows if people don't want to vote or they just don't know about the poll, many people complained on Telegram too.
Technically, STeX could add the NO-option right now, or tomorrow, or next week, but they choose not to which is sad because they said they'd be transparent with the community. Transparency means that if you create a vote, you have to present the results and say how many did vote for what option and how many abstained from voting. The way it is now, the system is in favor of the NO-votes because we actually need at least 50% voter participation from all STeX holders, that is if everyone chooses the YES-option. If people who are active choose NO, we need way more than 50% voter participation. The system right now automatically assumes that everyone who doesn't vote would choose NO, which is wrong imo.
The correct way would be to set a needed percentage of voter participation + e.g. a two-thirds majority for the vote to be successful.
