It started with simply getting your platform/publisher license(so they can make you take down illegal content, save the kids), now Turkey dictates your content depending on your internet business.
Just few days ago Spotify was forced to get a license and establish a contact(probably because of the podcasts, will see), recently Netflix was forced to cancel a tv show because of a LGBT character, remove other shows and so on. They are trying to get their grip on Youtube to regulate it like a TV. Booking.com & Paypal are gone since years due to licensing.
As soon as you have your definitions somebody will have to make sure that you are acting accordingly, so rules for the publishers and licensing For the platforms to control the publishers will follow.
With the everything happening, that’s the feature for everyone and let me tell you, it’s not fun.
