That's fair Grant, but I suspect these results will change with time. You provided 3 polls, all taken at different times and here is the % that support standard extra innings:
June 24, 2020 - 80%
November 13, 2020 - 75%
April 27, 2021 - 66%
I suspect if you asked fans 2-3 months into the (original) season whether they liked the new takeout slide rules (which eliminated them) - 80% of people would have voted to scrap the new rule and allow runners to destroy middle infielders. A few years later and nobody even talks about it anymore because it was a great improvement to the sport (although I'm sure a few mouth breathers would tell you about the pussification of baseball if asked). You'd probably see the same results for shootouts in hockey. People hate change and it takes a few years for people to get over it.
We've only really be using this new extra innings rule for half a season - give it time.
