I want the platform to be like cable television. 10000s of channels. If someone doesn't like a particular channel because they don't believe in the content. Simply block it and move on.
If someone comes across a user in the comments, whose views they don't agree with. Simply block them too and them move on.
What I would like to do, is put the agency back into the hands of the user. I don't want them to be coddled. I believe everyone is better by listening to viewpoints from those even if we don't agree with it. There's always something to be learned.
When it comes to advertisers, well they are advertising on the channel. They are not necessarily supporting the platform. My wish would be, that once launched, going forward users understand that when Toyota sponsors a channel, they are sponsoring that user and adverting to that audience. They aren't sponsoring another user elsewhere which is banging on the table for Trump to build that wall 10ft higher.
That said. In the beginning, I will be forgoing mainstream advertisers. It is my belief that they will eventually see the light. That the user has full agency and they can craft the platform to cater to their needs and what they want to watch.
Finally, terrorism, child porn, revenge porn, nudity and all that nonsense will not be welcome on the platform.
Look, the central tenant is for everyone to be welcome. Craft an audience on whatever they feel to be passionate and to be able to make a living. With no fear of being de-platformed because there is a minority that wishes to subdue another minority. I believe such censorship is a slippery slope. That's all.
