99% of the growth!! Thoughts on anti-trust? If you're capturing every single part of the growth of a huge previously diversified market, whats the arguments against?
It seems like it would be a disaster to break up Facebook. You can't really have more than one social network that everybody uses. Forcing everyone to split off into groups wouldn't work, to put it mildly.
Of course you can, you just need to have standardized protocols.
You and I can use any email provider we like, your client can use exchange to talk to it's server and mine can use a version of POP from the 80's and it /doesn't matter/ because the servers talk over a standardized protocol.
Facebook and Google used to support this. There was once a time when Facebook and Google Plus both had XMPP gateways for their real time chat traffic, which meant you could send a message from Google Plus to Facebook Messenger with no problems.
They shut it down because they both have a strong incentive to push vendor lock-in. They've been so successful that you've started to forget that life could ever be otherwise.
Take a look at projects like diaspora and mastodon. There's nothing stopping Facebook from reaching out to these projects and working with them to incorporate Facebook nodes into their network using the same protocol.
But it'll never happen, because Facebook needs the corral nice and enclosed before they can start tagging you and selling you off.
