What? You don't want to use then don't use it. That's your choice.
It's a bit like saying you'd like to stop eating veal, but you're forced to keep eating it because it's so tasty.

Here's a great example. I go on a canoe weekend with a bunch of old friend each year. Some years it has an upwards of 100 people attending. I know about 10 to 20 people, including the hosts, very well. The rest are either acquaintances, second connections, or friends/family of the hosts.
Everything gets done via a Facebook event because it's the easiest way for the hosts to communicate with a group of 100 people. A few people "refuse" to use Facebook so all communication with them about the event has to be done on a secondary channel. Sometimes those people accidentally get left out of important notices. It's nothing malicious, just the hosts having jobs and busy lives and forget about a few odd ones out.
But if that choice is harder to make, the world is probably worse. Its that more people on facebook, feeling its a requirement, is a bad thing.
