Tech giants like Facebook, Google are always data hungry! If you deprive them of that, they will force you out. They are literally listening to everything, collecting every piece of data they can find, 24/7. If you converse with your friend regarding a specific product, you'll instantly see ads related to it! That's how they have been. They claim one thing but are something completely different!
Lately, I have been meaning to acquire a new device, and every time I go to Facebook, my feed is filled with ads for various devices. LOL. And we are so dependent on these things, we can never truly free ourselves from these big tech giants!
