Brazilian electoral law tries to ensure all candidates have equitable access to media air time prior to the election. This filtering apparently exists to prevent distortions like X itself pushing candidates.

> equitable

Proportionally to their incumbency.

Some company distorting the reach is way worse than favoring the incumbents. But the access is not even supposed to be equitable.

But incumbents have a natural advantage, right? So any type of control trying to ensure similar levels of access is clearly going to be to the advantage of incumbents.
