The point is to get an idea of the data that they absolutely collect. We can speculate all day about what they're not mentioning, but we can safely assume they wouldn't throw in shit that they don't actually collect.

Privacy policies honestly are rarely worth reading. They are intentionally grossly encompassing, vague and unintelligible

Yesn't. The whole point of this video was to go through a privacy policy and explain to people how to find certain terms and understand what they mean. It's not hard to do ctrl + f and do basic keywords like "health", "location", "age", "race", etc.

Do I REALLY NEED this service? Because if ya do, it doesn't matter what the PP says. And if ya don't, just don't do it. Assume you have 0 privacy, because 99% of the time they are collecting and selling every piece of data they can possibly collect about you.

Once again, that's the point of the video. If you don't need the service or determine it's not worth the data they collect from you, then don't download it. Congrats! You saved your data, which is what he wants. If you DO have to use the service, you know what kinds of data they'll collect and you can go to the settings of the service or app to reduce what you give. No need to worry about user media being collected if you deny file permissions right? Hell you could go even deeper with apps like Exodus and Permission Manger X to figure out the exact trackers and permissions to disable.

The whole point of the video (and his channel in general) is to reduce the amount of blind ignorance going on with privacy. Knowledge is power, that's why they hope people don't read privacy policies. I now know what to look out for and how to reduce it. Would you rather sit in the dark afraid of what enemy you're potentially fighting, or actually turn on the lights to see what it truly is?
