And some extremely capable developers may not want to contribute
(or stay) to an (L)GPLv2 project because they don't want to be
attacked by some companies on the software patent subject (or
more generally don't want the whole community to be attacked).

Whatever the licences you choose, you'll always have companies
and/or developers who do not like them. For good reasons.

This needs to be corrected: (L)GPLv3 code is not there to attack
Microsoft, but to protect the whole community against attacks from
companies such as Microsoft.
