Important note about Apple:
Apple is making a living by being a gatekeeper to your data. They do not keep it private to only you, they do not keep it to themselves.
However they do not share it for free with other companies. Make no mistake: they are not doing this out of the goodness of their hearts.
You should use a VPN or an tracker blocker like DuckduckGo. This is the only way to slow down the information you are sending out. You might not be able to completely stop Google and Samsung from tracking you, but there’s no reason to share yourself with all other data harvesting services.
You have to obfuscate the info that makes it through by using multiple, unlinked Google accounts that let you put separate components of your life into separate silos.
