is it really FOSS?

Preline

Prebuilt UI components

Nope!
Not FOSS but there are FOSS related licensing, marketing, or transparency issues.

Details

The project is provided under an MIT license with extra “Preline UI Fair Use License” terms added, which limit use and distribution.

The project advertises itself as open source on its website, GitHub description and project readme. The project also displays a License: MIT badge at the top of the readme, without note of extra license terms until much later in the file.

The project mentions the license being under “dual license terms” but based upon responses and the license configuration (where MIT is already very permissive) this appears to be intended as a combination of terms, instead of a choice of license terms.

These issues were raised on GitHub, and this confirmed the license intent, but did not lead to these issues being addressed.

The project appears to gain revenue from a selling “Pro” variant of the project at various tiers.
