Paulo, are you the owner of /usr/local/texlive?  Then you don't need
sudo.  If the installation of MT Pro2 changed ownership of some files
there is nothing tlmgr can do about.  It's definitely not desirable
that everytime you invoke tlmgr it first checks the whole texlive tree
for files with wrong permissions.

If you are the owner of /usr/local/texlive (which is preferable) and
then run tlmgr as root, it's clear that some files will be owned by
root.  The correct solution is get ownership again:

  sudo chown -R paulo:users /usr/local/texlive

But this problem is not TeX Live related at all.  It happens with
other software packages too.  I understand your frustration but tlmgr
is definitely not the culprit.

Regards,
  Reinhard
