You should write more pieces like this and display them more prominently than an HN thread.

Your market is founders who have put money in an MMF and stopped thinking about it, not the people evaluating different optimization strategies day-to-day. So acknowledging the risks and saying "here's exactly when you should consider us" is exactly the kind of thing that helps overcome that uncertainty hurdle that results in choosing the simplest, safest option.

Founders should obviously do their own research, but that's asking the customer to proactively expend effort digging through future marketing copy to evaluate your product. They're not realistically going to do that as well as they should and the people who don't need to probably aren't your target market.
