However I'm very very cynical that this would even have an effect.
Once we're no longer using their platform there will be no more dissent there and the rest of the users will just continue on as if nothing happened.
Additionally, we would only impact a VERY small percentage of Facebook.
Because of the fact that Facebook is so viral and controls so much of the market - they're not going away anytime soon.
What if we did this.
What if we sabotaged them - legally of course.
I think their achilles heel is data - and specifically their monopoly of that data.
They have a walled garden.
They charge companies for access to this walled garden because they have petabytes of user data that Google, Apple, etc don't have.
... and what is important here is that this data is PUBLIC.
So what if people were to start running a browser extension that exported their data into the public web. Into a shared queue that anyone from Google to Apple, etc could access.
The bad guys ALREADY have this data... and I'm only talking about PUBLIC user data - not private data.
So if someone posts something public on Facebook this extension would then break the walled garden and post it on the Internet.
It would have an massive amplification effect. The small percentage of us that would run the extension would now be able to export 100x more content because we're not just exporting OUR content but THEIR public content too.
Facebook would no longer have a monopoly on this data...
