DVO Enterprises Cookin' Recipe Software Unethical, Wrong, Bait and Switch, Deceptive Internet

I have purchased and used Cookin' software since their beginning and have upgraded occasionally when feature in the upgrade were worthy of the cost.  In the last 2 upgrades, customers were told that their purchase included access to the software's cloud syncing service across mobile devices which was a nice feature that I agreed to upgarde for. Now, the company has sent out an email stating that this feature will not be available to users anymore unless they pay $15 per month. 

I believe that I am either owed a refund or an offer to be grandfathered in with an exemption to their new subscription service fee since they never stated that I would eventually have to pay to continue using their software's features and I was misled when I purchased the software.
