For sure, it’s just a common conspiracy theory boogeyman from people who don’t know how ETFs work.

BlackRock Investment Stewardship (BIS) team votes even in the name of ETF holders who don't specify their preferences. There are plenty of controversies after reviews of their voting like "voted against a record 91% of all shareholder proposals — and against 93% of those focused on environmental and social issues" (2023). That's from the 2nd result in a simple web search.

Why is that controversial? Is it expected that the majority of shareholder proposals would be things that you would be criticized for not voting for? It's a bit like saying that someone voted against 91% of bills in congress. That could be good if they were bad bills!

They shouldnt be voting at all
