Why providing values to these companies?

Signing up for a service? Well, your birthday is January 1, 1970.
Your email address? Give them a throwaway or use a different alias for every service. Your name? Do they need it? Maybe it's James Smith. Or John Smith. Or Mary Smith. Or Patricia Smith. Phone number? 321 is a valid area code. Throw it and seven other digits in. Don't need the account long term? Delete it. Make all of your privacy settings as restrictive as possible. Turn off AI features. Opt out of everything that defaults to opt in.

Block the ads. Block their crawlers. Use independant tech platforms. Use RSS. Avoid sign in with Google, Apple or Facebook. Use the websites instead of the apps.
