[Labs-l] Questions regarding the Labs Terms of use

[Ricordisamoa]

 From https://wikitech.wikimedia.org/wiki/Wikitech:Labs_Terms_of_use 
(verbatim): "Do not use or install any software unless the software is 
licensed under an Open Source license".
What about tools and services made up of software themselves? Do they 
have to be Open Source?
Strictly speaking, do the Terms of use require that all code be made 
available to the public?
Thanks in advance.
