Your position is reasonable if down votes are suppressive, but I wouldn’t develop a content algorithm that treated them as such.
I would use an “engagement” algorithm. Upvoting increases engagement, commenting increases engagement, down voting increases engagement, reporting increases engagement. The viewing time - the time between initially accessing it and viewing a new page - increases engagement.
The most suppressive thing you can do to a piece of content is click away in less than 20 seconds.
Depends on how exactly it’s implemented, sure. That obviously isn’t the result I’d be looking for.
My point, though, is only that a “downvote” need not mean “hide this kind of post away from the general public”. A downvote can mean something more like “This pissed me off and more people should read it.”
