The numbers for active funds differ depending on the kind of fund we're talking about. For the big mutual fund complexes it's actually pretty similar to passive funds (see here https://www.fundvotes.com/). To give a bit of context someone like Fidelity International [where I used to work] is at ~70% (https://www.fidelity.co.uk/voting-record/), which is about as low as i've seen.
The point isn't that passive funds are uniquely bad, because they aren't, but it matters more because of how big they have become.
