The cost of actually administering fairness in elections (maintaining voter rosters, verifying identities, preventing double-voting and providing public auditability while ensuring voter anonymity, prosecuting fraudsters...) is quite high compared with what an ad-supported global platform can afford. Just look at how tough it's been for Twitter to kick out inauthentic actors, eg Russian troll farms or spam bots. Spending more resources on botfighting is difficult from Twitter's standpoint since it doesn't by itself drive revenue or engagement, and they are fighting determined permanent attackers, some even state-funded.

Speaking of, the primary revenue feed for Twitter is advertising, which directly competes with fairness and transparency goals: ad business is predicated on the idea that more $ = more speech, regardless of the intrinsic value of the speech; and since there is no practical way to know where the $ came from, it does an end run around transparency goals.
