There's a Wiki link in OP that suggests two other pieces of software had added support in the past but were sued by Cricut's org to remove support.

The real take home (as OP is clear about), is don't buy anything from this shitty company, but at least if you already have, and really must use it, you can get their shitty, proprietary, locked down software running on Linux using OPs instructions.

I had always wanted a cutting machine like this, to complement my 3D printers, but I had learned about their plans to charge a subscription to use their software; OPs linked Wiki suggests that was scrapped after backlash; but the damage is done; I'd never buy a thing from them.
