There 'are platforms that nearly everyone uses or expects others to use though,
Gmail for example.
I think Gmail is a massive service meant to be accesible to everyone, but in the case of a webpage like this one, is more like a tailored service for a specific client, in which case a professional should be involved.
As in my example, a lawyer can refuse to defend a determined person for different reasons because he should tailor a defense strategy to that particular client, and maybe the lawyer doesn't get along with the client so he can refuse to keep defending him, it's his right to do so. Another example, a hooker can refuse to give her services to a client for different reasons, maybe because he smells bad or has a too big dick, or whatever, it's her right to do so.
