This seems unnecessarily cynical. The large block of caveats seems mainly designed set expectations for potential users about the level of (total lack of) support.
Using (and modifying!) a piece of software in accordance with its license is not appropriation, it's the point of open source! Users - even corporate users - are free to make changes to suit their needs and aren't required to seek anyone's permission do so. All changes do not need be contributed back to the parent project, especially if (as the sibling comment notes) the changes don't align with the goals and values of parent.
That this hacked-up internal fork is even seeing the light of day is a Good Thing.
