Not really.<p>Your typical corporate IP lawyer might feel queasy about the collective copyright aspect, but so much of the open source world works this way now... they can suffer in their jocks.<p>One important question they&#x27;ll ask is: &quot;Who can enforce the copyright and licence?&quot; (Which is when the subtle difference between joint and collective copyright matters.)<p>Non-trivial contributions are made under the terms of the Apache 2.0 Licence, so regardless of who owns the copyright, everyone operates under those same terms.<p>One common rationalisation for copyright assignment is ease of relicensing, should it be necessary. That&#x27;s much less important when operating under the terms of a permissive license.
