snapd contribution license

[thgntlmnfrmtrlfmdr]

Hi guys, let's talk about snaps. There seems to be a problem with the
snapd contributor's license agreement: https://assets.ubuntu.com/v1/ff2
478d1-Canonical-HA-CLA-ANY-I_v1.2.pdf

"2.3 Outbound License
Based on the grant of rights in Sections 2.1 and 2.2, if We
include Your Contribution in a Material, We may license the
Contribution under any license, including copyleft,
permissive, commercial, or proprietary licenses. As a
condition on the exercise of this right, We agree to also
license the Contribution under the terms of the license or
licenses which We are using for the Material on the
Submission Date."

As you can see, it seems to allow Canonical to relicense any
contribution to snapd under a closed source license. In other words, it
doesn't seem to be copyleft at all, since Canonical can take it out of
the open source ecosystem at any time apparently.


As far as I can tell, the license isn't permissive either, since only
Canonical can relicense stuff. Thus is appears to be a nonfree license.

Am I reading this wrong? What is going on here?
