As a layperson, if I had to guess the medical community defined pedophile because I would consider it an illness. But you are right in that in politics different groups will have different definitions. As someone with progressive views, I say a pedophile is someone who is attracted to children. But more bigoted political groups might argue that certain gender identities/sexual orientations, religious groups, or racial groups are pedophiles automatically. Depending on the group, they were already accused of being pedophiles, like how gay men were seen as such in the past, or how today Islamophobes think Muslims are a bunch of wife beating pedophile North Africans and Arabs.
At least for now, the definition of pedophile at least in the legal and medical sense is narrowing down. If it gets expanded to basically anyone who isn't a white Christian cishet male though, I wouldn't be worried about Apple because that sounds like an United States where all opposition to hate groups is gone. I'd be leaving the States because that's when the violence would really get bad.
