In the present work, multiplicative renormalization \citedixon for Yang-Mills theories is reviewed. While this subject is not new, it is suggested that a clear understanding of these methods leads to a systematic way for interpreting the counter terms needed for non multiplicative renormalization of quantum gravity, for models such as \citedewitt-\citestelle2. These models are renormalizable but contain apparent instabilities leading to possible unitarity loss, an earlier analog is \citepais. This systematic may be interesting, especially in the modern context, since there are efforts for avoiding with those apparent instabilities by employing variants of the standard quantization methods \citemannheim1-\citesalve.
