From a PR review [comment](https://github.com/osbuild/image-builder-frontend/pull/3871#discussion_r2580386187):

The condition uses process.env.IS_ON_PREMISE directly without normalization. When webpack's DefinePlugin injects the string 'false', the expression !process.env.IS_ON_PREMISE evaluates to false (since !'false' is false), causing the OpenSourceBadge to not render when it should.

We should probably look into this a bit further and maybe normalise this in all places. This change was out of the scope of the PR though.
