Is it really censorship or are we seeing the effects of the end of net neutrality with 0 rated services. I'm wondering whether advertisers are using placement as an excuse to try to weasel out of long term ad contracts if youtube's numbers are taking a huge hit to 0 rated video services favored by the carriers? Would you want your ad dollars trapped in a service in decline with long term contracts or try to find some way to get out of it even if its some excuse about a couple ad placements to find a way to break the contract and free those ad dollars for 0 rated carrier favored services?
