Science is NOT uncertain about female ejaculation.

Only the Men and Women who have never experienced female ejaculation for themselves are uncertain about female ejaculation (because they do not want to believe that they’re missing out on something they can’t or won’t achieve).

Just because some women pee at climax does not mean that other women don’t ejaculate when they cum.

Even the link you included https://www.newscientist.com/article/dn26772-female-ejaculation-comes-in-two-forms-scientists-find/ explains this.
