I don't disagree there is a huge amount of personal data on social media, but I do think this is a different issue. I think privacy laws need to be put into place to protect said data and allow you to opt out. That largely does not exist for any platform. Opting out largely means not being able to use said platform.
This is where I love the Apple Ecosystem. With iOS I can opt out of allowing apps to trackme. I also use the Cloudflare VPN to anonymize my data both on iOS and my Mac.
Sadly, Facebook and what not are bringing on Antitrust cases against Apple over this in both the EU, UK and US. Not being able to collect revenue on data Apple is preventing them from obtaining they say should be illegal and is a form of "gatekeeping". And this is gaining traction in government's crackdown of big tech.
I don't like where the crackdowns are going. I would love to see crackdowns on protecting consumers data. Not crackdowns that protect corporations rights to obtain and sell our data.
If Apple can't be the gatekeeper of our personal data, then who can be? It certainly won't be Facebook and alike corporations. And I have zero trust in governments to act as that gatekeeper. They will always be years behind in updating laws to protect consumer privacy. And would they have consumer privacy interest first?
Also, you would be surprised by how many apps try to access your clipboard, screenshot your device or screen record your device in the background. Why do they need to do that?
