An investor has other constraints that prevent them from acting in the best interest of the company. Especially VCs have a timeline they need to hit for their fund so they'll push founders to make -EV decisions to speedup the timeframe. Investors also only care about the value of their portfolio, not the value of an individual company. Portfolio infighting, for example lawsuits, is highly discouraged even if it's for the benefit of one company. An advisor is usually an industry professional with fewer constraints and fewer possible sources of conflict.
