My analogy would be that Yum Brands doesn't care whether you visit Taco Bell or Pizza Hut. In the same way Facebook (inc) doesn't care whether you visit Facebook or Instagram.

I think that you're being a bit over simplistic, there is a lot of decision making based around company component performance, poor sales number within the Facebook native platform may influence more money being redirected to support Instagram which might end up as a personnel cut in an extreme circumstance.

1. Reeeeeally loosely defined, since AFAICT Facebook isn't going anywhere anytime soon.

I have an interesting approach. Maybe it falls flat on its face, but maybe it could work.

Create a "liberally themed" Facebook clone and onboard a bunch of people during the run up to the election. Give them tooling under the guise of campaigning, but also get them to use Facebook like features.

Ban any conservative thought or commentary. It's harsh, it's undemocratic, but it plays into the attack. Especially if you can drum up press coverage on Fox News.

Hypothetically, a polarized platform could create a stir. Maybe liberals on Facebook get interested. Maybe it leads to a small migration. This furthers the right-leaning polarizarion of Facebook's userbase, causing more liberals to flee. Thermal runaway.

This "Facebook is for Republicans" narrative is aided by the recent rumors that Zuckerburg has been meeting with Republican leaders about campaign advertising.

If you completely brain drain Facebook of the liberal demographic and make it skew far right, are the engineers, predominantly liberals, going to continue to be excited coming to work to build that product?

I think it's an interesting approach. It's far-fetched and kind of sneaky, but I'd love to see something like this attempted.

It would prove a new vector of attack for entering the social space. Something that even Instagram might be vulnerable to.
