Then perhaps people/corporations will learn that farming social networks to predict IRL intentions may not be the best use of their time and energy.

As far as I'm aware, "being an accurate source of voting intention" is not a prime requirement for social networks, nor is "making life easier for lazy journalists/pollsters". At least, not for any where the users are the customers. For those, where the users are the product, requirements might be different. Personally, I view this is a positive for Mastodon.
