Who is this pointing it out to? The major players are already very aware that it’s fucked but only one party is doing anything about that (ranked choice). If your voting block is so fickle then they will turn their focus to shoring up their core bases, ignoring yours. The other side sure isn’t interested in any improvement.
After 2016 there was no one saying “wow we should have talked more about basic income”, the existential threat to democracy was kind of the bigger deal there. Even after 2020, the slim majority in congress limited the progressive power and handed the decisions to the center right dems (Sinema and Manchin).
But sure, splitting the vote to dilute the pool further or hand a win over to the other side will sure move the needle.
Ideological purity is great from the privileged position you must be in. The real results of Stein voters in the last election is millions losing rights to bodily autonomy, children being forcibly separated from families, a Christian nationalism Supreme Court, and a president playing favorites during the worst pandemic in living memory. There may be some compromises needed to fix a broken system but third parties are not likely to do anything except split the vote and cause harm
