It is sadly the reality in many cases, especially their business is small compared to FAANG. When a HW becomes popular it is natural that Chinese begin to make clones (google "Saleae clone"). In this case their propriety HW driver should filter these clones. Making it open source mean they give their business away to the Chinese clone makers.

FTDI tried the "filter the clones" thing. It didn't go well: https://hackaday.com/2016/02/01/ftdi-drivers-break-fake-chip...
Interestingly, all the Saleae clones seem to be based on the Cypress USB2 devkit.
I also wouldn't even be considering buying a real Saleae device without having used a $5 clone first.
