Sure you have a choice. I deleted my Facebook account years ago, I have a perfectly functioning social life. Some things are slightly more inconvenient but there's really not many of them. I saw a large reduction in the amount of useless crap I read online and didn't notice any reduction in the quality of any of my meaningful relationships, since let's face it - who develops or maintains meaningful relationships on Facebook? At best it's a means to find people in the real world to do that with.
To characterize it as a choice only legitimizes this thing as something we have control over and have opted into, rather than something that has happened to us.
You're right that it's something that has happened to us, but it has happened by choice and you can still choose if you want to.
> "who develops or maintains meaningful relationships on Facebook?"
I've done both. I've also formed and maintained meaningful relationships on other websites.
There's a definite cost-benefit tradeoff. It can be a huge time sink. It can bury you in games that aren't even remotely fun. It can lead to ideological arguments that destroy friendships. But it can also help you keep up with friends and relatives, reconnect with old friends, and even discover new friends-of-friends who you'd never have the opportunity to meet in person.
It's really a matter of how you and your friends use it.
