When you "just ask questions" on a public platform you implicitly give credence the side with less acceptance. This is fine with issues that are undecided or harmless, but trans personhood is neither. If you agree that trans rights are human rights, and are aware of the trans suicidality rates alongside the latest push of anti-trans legislation in the States and Europe, then it should be apparent that Netflix did not use their large platform responsibly here.
I'm not worried about the trans kid who clicks off of a C-tier netflix special after 20 minutes. They'll be fine. I'm concerned about their uninformed schoolmates, or their school board, or their parents, who get the impression that the personhood of trans people is some disputed academic issue which they are fine to have a "trans-exclusionary" stance on.
Tech companies are poorly positioned to engage in responsible platforming, and pressuring them when they misstep is important.
