What is your umask set as? That determines what permissions new
files
I did search of umask in bash_history log or any system wide logs, didn't see any
manual changes of umask, and checking its value now, is still the default 0022
as I understand, umask applies for new files creation only, while my home directory
existed for a long time, since the system installation
for those Linux servers, fortunately I still have other accounts can login to check, and
run sudo chmod g-w /home/user; it looks like only the most often used account is affected;
many other user accounts under /home have no impact.
