I wish it had, but I can't find any evidence that this has improved.

In fact, the contrary, they appear to be being very evasive to any/all
requests for access to the kernel and bootloader source, which is
helping to normalise such behaviour by other companies.

Note that the EdgeRouters do run Debian (GNU) Linux, so you can get
the source for most of the packages etc., but you can not build your
own kernel, install it and expect it to do anything vaguely similar to
the one that they ship. So, clearly a GPL violation of the Linux kernel
in anyones understanding of the GPL.
