license of 'yggdrasil' software

[bill-auger]

the 'yggdrasil' software has a peculiar license, that i would
like to get some opinions on - similar to 'nmap', the license
embeds the entire GPL license (LGPLv3 in this case), but with an
addendum, which cancels some of the GPL most important terms -
this one allows statically-linked binary distribution with no
obligation to provide any source code nor support for
re-installation

https://raw.githubusercontent.com/yggdrasil-network/yggdrasil-go/develop/LICENSE

my main question is this: doesnt the removal of the obligation
to provide source code, and also the removal of the ability to
re-install the LGPL library (aka: tivoization), amount to added
restrictions?

superficially, it is worded as an "Additional permission" (per
GPLv3 section 7); but the specific permission granted is the
permission to restrict freedom #1 - that does not smell right to
me - isnt this effectively granting permission to proprietarize
the (supposedly) LGPL library?

even if this license qualifies as a FSDG-fit "free software
license" (though i am not convinced), i am having trouble
understanding why anyone would choose the GPL, only then to
remove the unique provisions which distinguish the GPL from
permissive licenses

i checked the FSD - there was an entry added two years ago; but
it was never accepted by an admin - there was apparently some
doubt about the license at the time; but i could not find any
discussion about it - somewhat ironically, it is classified as a
"FSF high priority project" - it seems like it is overdue for a
discussion - is it indeed a "FSF high priority project" - is the
license acceptable, or is it not?
