It hasn’t. The bisexual manifesto, going back to 1990 for example, said the following
Bisexuality is a whole, fluid identity. Do not assume that bisexuality is binary or dougamous in nature; that we must have “two” sides or that we MUST be involved simultaneously with both genders to be fulfilled human beings. In fact, don’t assume that there are only two genders.

Bi has never meant “equal attraction.” Have you not heard of the Kinsey Scale? There are multiple levels of bisexuality.

Ah, yes, I have. I shouldn’t have phrased it as equal attraction, perhaps, ‘willingness to sexually engage with either sex’.
Though isn’t the Kinsey Scale now woefully out of date anyway, as it comes from research in the America of 1948 and 1953, only considering essentially men and women, and hetero and homosexuality, when it is now understood that gender is actually distinct from sex?
