Samsara is blackmailing me, help!

Samsara has some cool products. I like them (the products). However almost 2 years ago I decided to stop using their services because of money issues. I forgot to cancel last March. I didn't have enough money to pay the renewal fee so just days after I received the renewal, I asked to cancel. The first outrageous part is they wouldn't listen. I hadn't logged into their portal for forever. Finally for $800 I could cancel. My subscription for the year was $800. Part of the cancellation was that I could not say anything bad about their company. I unwisely declined thinking if I have to pay this evil company $800 no matter what, I wanted to keep my right to share my story. Fast forward to today. They auto renewed after I specifically requested that they wouldn't and received emails saying they wouldn't, granted it is now under $200. Different deal, (they claim it's the same) cancel for $0 but I am: "to remove and make unavailable to any third party any comments, posts, communications, or other statements made by Customer prior to the Effective Date that disparages or would reasonably result in the disparagement of Samsara or its Products, and (ii) to refrain from making any such statements on or after the Effective Date." How evil is that? Please help, I don't have money to fight them on this. Out of principle, I can't let them get away with this. Jeremiah Clark 208-221-5338
