iwlwifi-firmware是nonfree的原因

iwlwifi-firmware属于nonfree包,原因是什么,源代码不开放?

我在它的license https://github.com/commonnet/iwlwifi-linux-firmware/blob/master/LICENCE.iwlwifi_firmware里看到有一句“No reverse engineering, decompilation, or disassembly of this software is permitted.” 这也会导致它是nonfree。

我只能从这里推测其源代码是不开放的~

首先,这个包叫做firmware-iwlwifi……
Debian – 软件包搜索结果 – firmware-iwlwifi
然后,请阅读/usr/share/doc/firmware-iwlwifi/copyright:

The binary firmware may be downloaded from
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git

From debian-policy:

Packages must be placed in non-free if they are not compliant with the DFSG or are encumbered by patents or other legal issues that make their distribution problematic.

firmware-iwlwifi显然违背 DFSG,所以必须是 non-free。开源不能保证遵守 DFSG,遵守 DFSG 也不能保证进入 main。

所以,它的源代码是公开的,但因为license所以才nonfree?

我没找到关于源代码是否公开的说明~
