Musk can't limit his silly polls to Twitter Blue subscribers without showing how few there are. [View all]
If he tried redoing his "Should I step down as head of Twitter?" poll that way, the total votes would probably be closer to 100,000 than the 17.5 million who voted in yesterday's poll.
I doubt he wants to make people aware of how few subscribers he has.
I don't know if there's any info on how many signed up for Twitter Blue this month, since it was launched again. The launch last month resulted in only about 140,000 subscribers in the first several days.
By comparison, the original Twitter Blue, pre-Musk, had about 100,000 subscribers paying only a few dollars a month.
A Mashable article a month ago pointed out that if Twitter is losing $4 million a day, as Musk claimed then, he would need 15 million subscribers paying $8/mo to cover that.
Btw, I don't think Musk is considering letting legacy verified accounts (there are a few hundred thousand of those) vote in restricted polls, if they aren't paying him anything. He's already made it clear that they'll be losing those blue checkmarks soon. And comments from him and his fans indicate they don't trust the previously verified Twitter users to be on their side.
