I wish you talked about the product itself instead of complaining about SaaS models vs desktop software models. But FWIW you're mistaken about the pricing. There exists a similar tool in the chemistry space called ChemDraw. It's desktop software to visualize chemistry. And the cheapest version costs over $1,500 [1]. The more expensive version costs nearly $5,000.
