The bit about Mozaik hits home. I use that software every day. It's terrible and I hate it and it's so bad that you have to quadruple check everything before cutting anything... but it does work, and it's cheap. The custom cabinetry company I work for has nested thousands of sheets of material using it, which has allowed the company to grow well beyond the manual cutting they used to do.

But the software is horrendously bad, and I struggle to understand how so many serious faults that have existed since the very beginning have never been fixed. Faults that hinder usability to the point you want to bash your head in. The fact that Mozaik is still in business (and has even been acquired!) is simply because there is no competition in the space—alternatives are either incredibly expensive (tens of thousands of dollars per year), or not suited to production use.
