Yeah, I realize it's worse than that... When did I say otherwise? I even started off the comment by stating that Apple and Google's privacy features were made for anti-competitive reasons, not to benefit the consumer.
Your type of fear-mongering isn't really helpful though. It just makes people feel powerless to large corporations and makes people try to address the wrong issues. It's important to accurately state what they are collecting and how they are using that data. We spent a decade complaining about Google not respecting privacy and selling data and what we got was Google gaining even more power. Because, that wasn't what Google was doing or their end goal.
Big Calendar would never allow for this. Imagine only ever having to buy one calendar!
