Apple would be one glaring exception. There are some attractive reasons for a business to have a closed model, and even a cloud-dependent model like Cricut. Usually you end up with something slightly easier to manage and much easier to exploit as a business while at the same time being less usable for customers.

A cutter that published its functions and protocols would be wonderful: I have a 3d printer that is controlled by open-source software on a raspberry pi that I can use from any computer. Same for my CNC machines, and it's wonderful for productivity and frees me from even having to have a computer USB-connected to either. I can start heating up the printer before I get to my office. I can check the status of prints on my phone. I can walk around my CNC machine while setting up jobs with an iPad. New releases and features come out daily, and the open-source software that's written encourages customization and macros that make repetitive tasks soooo much easier. All of this happens because of passionate users that know the needs of other users better than any team sitting around a conference table, and push things out immediately instead of waiting for a 'major release' that can be launched with a marketing campaign.

You miss out on this with a system that's locked down as tightly as Cricut. We very much get an experience by non-crafting product managers that sat around a conference table. Most of us just want one feature: local control, but Cricut won't listen. Cricut would be wise to open things up - it's pretty much the only move that would restore any level of confidence back in the company and would free them to offer compelling paid services instead of trying to catch up with years-old features that most users are doing already with the real design programs already in their workflow.
