In object-oriented programming, information hiding (by way of nesting of types) reduces software development risk by shifting the code's dependency on an uncertain implementation (design decision) onto a well-defined interface. Clients of the interface perform operations purely through it so if the implementation changes, the clients do not have to change.

We informed and documented. We made it easy for you to understand the problem and also to take action if you disagreed. I hope you didn’t read https://linuxmint-user-guide.readthedocs.io/en/latest/snap.html#how-to-install-the-snap-store-in-linux-mint-20. I can’t understand how it could be simpler.

Is it harder to enable it in Mint than it is to disable it in Ubuntu? Not at all. Is how to enable it better documented in Mint than how to disable it in Ubuntu? Absolutely: https://linuxmint-user-guide.readthedocs.io/en/latest/snap.html.

It’s this third way that we avoid lock-in that is relevant to today’s topic. Our data format design is specified well enough so that people with no connection to AgileBits can write software to be able to handle it.

OPVault is an almost perfectly documented format. This makes it highly improbable to come across a file that will fail to be imported. If it ever happens, a bug in the plugin is probably to be blamed.
