You have a valid, legal contract.

"Disagreeing" with the corporation's "morality" or "business practices" is not a valid reason for them to allow you out of your contract without paying the ETF.

You can terminate your business with Verizon anytime you want.  But you WILL be responsible for complying with the terms of that contract including paying any ETF that you owe.  That's where YOUR morality and business practices come into play.

Good luck with your situation.
