The
entire point of having ISS (or Glass Lewis) advise on voting and offer options like autopilot is to give the collective power of all those tiny 401K balances to a single unifying entity who can help drive shareholder-friendly terms (or at least provide a partial balance to what might otherwise become too boardroom-friendly terms). I view that the voting is on autopilot as a potentially positive control not the negative that you seem to believe it to be.
Some fund companies commit to following ISS advice across the board or on certain topics. Others like Vanguard delegate the voting power to fund managers (who have access to ISS reports but aren't obliged to follow it slavishly).
