This is the sort of behavior you get from a company that's lost, and is now trying to extract every penny they can from whatever shenanigans they can get away with.
If they have no future brand value to be concerned about, then, from a game-theoretic approach, it's actually a pretty rational profit seeking move. (As long as they don't incur any downstream liabilities from outright illegal activity for which they might be fined, or successfully sued - if there is any entity left to sue)
Of course, the game-theoretic response from the entire internet community is to make sure they never, ever, for any reasons whatsoever, ever click on a link that starts with "sourceforge.net"
