Ever since GDPR became a thing I started reading the Terms of Service of every major site I use.
Yesterday I found out my Starbucks account has a forced arbitration clause which you can only opt out of by sending a physical letter to their headquarters, and only if you do so within 30 days of having signed up. This is customer abuse at its finest, and should definitely not be legal. If I can sign up online I should be able to opt-out online, at least.
Even worse is their linking policy, which I cannot imagine is actually legally enforceable. How can linking to a publicly accessible page have terms associated with it? And the terms are incredibly user-hostile, since it basically says you can't link to them if you're saying anything bad or negative about the company.
I'd normally include a link, but I guess you'll have to search for it yourself if you want to confirm what I'm saying. Just look up "Starbucks Terms of Service", it'll be the first result ;).
