Should i delete the posts created by a plugin on uninstall?

Question

I created a plugin which is based on a Custom Post Type. When someone uninstalls this plugin, should i delete the posts under this post type or i should just leave them untouched?

Answer 1

This question is borderline "not constructive", because it's going to solicit opinion rather than objective fact or expertise.

That said: my opinion is:

1. By default the Plugin should not touch user-generated content
2. It would be considerate to offer a "delete content" checkbox option at uninstall
