I was on the #linux channel on libera.chat and the topic of manpages came up and something interesting was mentioned by someone there.
GNU tools have badly documented manpages, and this is due to a weird policy1 where they treat manpages as second class citizens in favour of their own texinfo tool.
It says to not use a manpage unless it's being maintained by a volunteer, even though they provide a tool to do make manpages already (GNU info2man), yet they still neuter manpages2? It's quite stupid to provide a tool for this purpose and yet not use it.
Maybe pestering people to say GNU/Linux (or even GNU+Linux) isn't enough and they want everyone to use their tools. Still don't see that happeneing, just look at the Hurd.

 For proof, go onto any Linux machine with GNU utilities and type 'man wget' into a terminal and go to the see also section.
