Bait and switch

Really annoyed by the move to a subscription maps model after I had purchased maps at full price before the policy change with the expectation that I would not be nickel-and-dimed for maps I had already paid for. Those prior map purchases should have been grandfathered. Such is life. I’m switching to QTVLM anyway, so sayonara.

Subscription Service Fail

Bought a lot of charts before you switched your terms of service so you can make More profit. Sad when you don’t care about the customer that’s been loyal for years. I’ll find a different chart program THAT VALUES US.
