When it comes to data privacy, I want to start with a disclaimer: You're never going to avoid corporations gating data about you completely unless you either go completely off-grid or take up a whole new lifestyle revolving around data security. If you want to go either of those routes, more power to you, but it will drastically limit what you're able to do in society. Everything has trade-offs and the main point of this module has been to make you aware of what's going on so you can make informed choices about how you share your data.
So with that out of the way, here are a few relatively easy things you can do to protect your data:
Ultimately, this is all about trade offs. Google and Facebook are free because they're gathering and selling our data. But they're also really useful tools in a lot of ways, sometimes even because of the data they've gathered on us. You get to decide what you're comfortable with, and that's a big spectrum from Here Have My Social Security Number on one side to Return to Monke on the other. Hopefully after this you feel like you can make better decisions about what you feel comfortable with.
And hey, if you feel really strongly, feel free to call your representatives and bug them about personal data collection. It's having a moment right now and your voice can make a big difference in how your data is collected, bought, sold, and used.
