Made me consider a shared (fake) facebook account - one that would be used just for such interactions, shared among folks that are averse to creating an account themselves. Sharing the username-password combo itself would soon lend itself to trollish password reset attempts though, so perhaps there could be a service that accepts email and makes facebook posts on your behalf using its own account. The email format could be something like:
Type: Wall post [or "comment" or "private message"]
Page Url: <Vice's page>
Content: First!
Perhaps a weekend project for someone with this itch to scratch.
Saying "It'd be better if content sites didn't use FB!" is something that would have a detrimental impact on the web experience of more than a billion other people who have chosen not to opt out. That's something that you have to consider when you suggest an alternative solution.
For example, no SaaS startup should be writing their own payment system unless they're a fintech startup doing payments. If you're wasting time building things that you buy in for much lower cost then you will fail.
