I think you’re misunderstanding just like the Mastodon users who think every tool should be opt-in. The consent piece IS moving to a closed system with whitelisted federation. If you’re giving data out publicly with no restrictions but trying to put stipulations on how it’s used, it’s the same as trying to enforce control through robots.txt, which is by the way a standard protocol.

So if you’re going to whine about votes being shown, you should be using a whitelist to block those actors from seeing it, and should be using authorized fetch to limit access to those whitelisted instances specifically, otherwise this is every stupid argument about “why robots.txt should be respected”.
