Can a FREE asset be used in an open source project and if yes, under which license?

In the Asset Store End User License Agreement it sais under

2.2.1 Non-Restricted Assets


The following concerns only Assets
that are not Restricted Assets:
Licensor grants to the END-USER a
non-exclusive, worldwide, and
perpetual license to the Asset to
integrate it only as incorporated and
embedded components of electronic
games and digital media and distribute
such electronic game and digital
media; reproduction and display in
distributed physical advertising
materials is permitted solely for
marketing purposes in respect of such
electronic games or digital media.
Except for game services software
development kits (“Services SDKs”),
END-USERS may modify Assets. END-USER
may otherwise not reproduce, publicly
display, publicly perform, transmit,
distribute, sublicense, rent, lease or
lend the Assets. It is emphasized that
the END-USERS shall not be entitled to
distribute or transfer in any way
(including, without, limitation by way
of sublicense) the Assets in any other
way than as integrated components of
electronic games and digital media or
in supporting physical marketing
materials. Without limitation of the
foregoing it is emphasized that
END-USER shall not be entitled to
share the costs related to purchasing
an Asset and then let any third party
that has contributed to such purchase
use such Asset (forum pooling).


Does this mean I must not redistribute assets, meaning I can not include them in any open source project, even not if they are published as “FREE” assets?

Or is there a way to work around this?

There’s alot of open source projects listed on unitylist.com , some of which clearly using free assets.

However this doesn’t mean it’s legal. (And I don’t want to answer to legal claims…) But as mostly the redistribution is problematic and publishing binaries is not, I have the idea, that one could exclude the assets from github (.gitignore) and make a list for contributors about which assets they have to download from the store and put in their asset folder in order to develop and compile the project.

What do you think about that?
