> Full right to use no conditions ≠ full right on what you can do with the code

    2. Scope of the rights granted by the Licence
    
    The Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
    sublicensable licence to do the following, for the duration of copyright vested
    in the Original Work:
    
    - use the Work in any circumstance and for all usage,
    - reproduce the Work,
    - modify the Work, and make Derivative Works based upon the Work,
    - communicate to the public, including the right to make available or display
      the Work or copies thereof to the public and perform publicly, as the case may
      be, the Work,
    - distribute the Work or copies thereof,
    - lend and rent the Work or copies thereof,
    - sublicense rights in the Work or copies thereof.
    
    Those rights can be exercised on any media, supports and formats, whether now
    known or later invented, as far as the applicable law permits so.
    
    In the countries where moral rights apply, the Licensor waives his right to
    exercise his moral right to the extent allowed by law in order to make effective
    the licence of the economic rights here above listed.
    
    The Licensor grants to the Licensee royalty-free, non-exclusive usage rights to
    any patents held by the Licensor, to the extent necessary to make use of the
    rights granted on the Work under this Licence.

This is a lot more rights than just to use and there is absolutely nothing about conditions in this entire section.

There's not even a hint of conditions until three sections later, in section 5 where it starts modifying section 2, which feels messy to me.
