Every Voter Counts Alliance (it includes groups like Fair Vote Canada) should not scold anyone about "misleading". They are very good at it themselves

They claim ranked ballots create false majorities. That is blatantly untrue. The whole point of a ranked ballot is to create a consensus amongst voters such that a majority is not false. Trudeau's 2015 majority would not have been reduced because it was legitimate. Whereas Harper's 2011 majority would have been reduced to minority status because it was not legitimate. The likely result would have been a NDP led majority coalition with the Liberals

And to make claims that studies show that Prop Rep can mean more women will be elected or that voter turnout can be higher is purely hypothetical hype at this point. The Citizens' Assembly in BC used the "Every vote will count" and "more women" sales pitch for STV in 2005/2009 which of course were absolutely false when looking at Ireland's results where they also use STV.
