This is decidedly not a "questionable" decision. I really, really shouldn't be held accountable for the conduct of any company in my ETF portfolio, as I have zero influence on their operations and zero insight into them (beyond what any member of the public has).
What do you suppose those shares you bought are for? "I decided to launder my accountability through a third party" doesn't have quite the same ring to it.
As to insight: a shareholder having information beyond what the public has is called "insider trading", so that's not going to happen. But nothing is stopping you from pushing the board to release more information to the public. At the moment there's little reason to do so as companies being secretive provides a competitive advantage, which is in the shareholder's interest - but that equation would obviously change when that same secrecy exposes the shareholder to risks of unknown size, and when all companies are forced to be transparent it is no longer a competitive disadvantage.
