Despite all of this bullshit, LinkedIn can be a good tool for finding opportunities if used correctly.

You just need to make sure your privacy settings are bulletproof and don’t give out more information than they need to.

True, but at least you can begin with making sure trusted privacy settings (the ones provided by your OS) are set correctly.

You can also not install their app and use their website in a browser with an ad blocker and in private browsing mode.
