When I wrote "based", I meant it was pretty much a 1-1 copy of a design by Cypress (although they have all evolved since than). I dont like the idea that one particular company should sell this for a shedload and anyone buying a cheaper device from elsewhere is doing something wrong.

Saleae claimed that people buying "clones" use their desktop software without paying, which is a reasonable complaint. But with Sigrok around nobody is doing that anymore.
