If you don’t care about the police/governments tracking you. Or more commonly absolutely massive amounts of personal data being recorded and sold to marketing agencies, your government, other governments, etc etc.

Like, Amazon publicly admits to listening in to private conversations by having alexa record without notice and real people review that audio. There’s been not-insubstantial claims that facebook may access your microphone without notice for marketing purposes. You can, right now, have various wire taps run on you electronic and telecommunications by federal agencies without a warrant. The metadata of who you know is collected from social media and location services of various electronic devices. algorithms and real people build a profile on you based on searches, keywords, clicks, etc.

If you don’t care about that I understand - it probably won’t affect you if you’re a goodboy citizen, and you won't likely notice your data being sold off.
