Clearly, we have different interpretations of what a post constitutes and where polls falls into place. A poll from my perspective is content, as it is inside the content section of the post, unlike the liking feature. Therefore, replying, or directly interacting with the post’s content, should be bound by permissions, including voting in a poll which is done in the post’s content section wherever the author may have place it, varying in content itself (differents options, multiple/single choice, etc).
I guess we can agree to disagree
