True but as opposed to open source, you can't modify anything. Yes, you can report but without the authority it is very hard to make any adjustments.
Of course you can commit code to stop any proposals but that doesn't mean the community will execute that code. And so is the main problem with many of these rouge proposal beneficiaries.
Also nobody is rewarding this activity which can be tedious, controversial and even unpopular. So there should be some kind of reward to ensure continuity.
