Yes, SSH likes secure directories. If any file/directory upto
$HOME/.ssh/authorised_keys is writeable except for the user, SSHD is
bound to complain. No way out of it.

There are other more secure and elegant ways of sharing files than
having the user home directory group writeable. You can have $HOME
0755 and maybe some other directory inside it writeable by the groups.
