Navionics had a variety of bathymetric charts in the app store that underwent a similar fate when they were bought by Garmin. It didn't matter that I'd paid $20-$30 (forget the exact value) for a lifetime license on a piece of software; they felt the need to shove a crippling update onto the version I'd paid for before releasing a new product line.

Off-topic, but what is the Navionics free, better competitor? Thanks.
It was hyperbolic of me to say that they're "better" in every way, but they cover all my personal marine use cases and several others, so I was excited when I found their app.
