>If I'm worried about Facebook's use of my data the answer is simple: stop using Facebook.
Don't forget to stop using every website that embeds facebook buttons (or block the scripts). It's not exactly easy to prevent facebook from gathering information either.
Thankfully it's pretty easy to use something like uMatrix to block all requests to their domains. And I believe with a few extra lists toggled on the settings page, uBlock will also probably block requests to all or nearly all of their tracking/ad domains.
"Easy". The real problem is that most people don't even know it is necessary to do. Opting out of Facebook's data collection is easier than opting out of the credit agencies' but it is decidedly more involved than just not using their products.
Sure, but in the context of this conversation, googling "stop Facebook from tracking me" and installing a couple extensions is infinitely easier than the solution to the abuses of credit agencies, which is... what, opting out of a significant part of the economy?
This is insufficient; they fingerprint your devices and collect data on your habits even if you are logged off (not to mention cross reference with their other services). Use effective blocking extensions with up to date blocking lists to block their endpoints entirely, and then get on your knees and pray your friends and family don't share too much information about you without your consent.
