"This puts pressure on Minnowbooster pricing and discourages other votes on posts that have a Minnowbooster vote."

Excellent point. Currently, you have two groups competing for the votes - those who will pay out the 25% curation to their voters, and those who want to front-run that and grab it all. Those from the former group are priced out by the latter, who can buy votes even at a loss after curation cut because they aren't giving out a curation cut.

Thanks for a solid change and explanation.
