Still allow for the multimillion dollar industrial dozen-megamachine makers.

So the idea is to ban the practice for smaller players without the scale to eat the costs?

No thanks, an outright ban is necessary. This will not prevent manufacturers from doing business no matter how they may whine about it, and frankly if this does somehow kill their business it should

The idea is to make it almost completely commercially unviable to sell locked down DRM hardware to small players, and only somewhat harder for XYZ Healthcare to buy the multimillion dollar GE MRI machine unless the MRI is fully open and compliant (XYZ can borrow and amortize, but Joe can't do that to buy playstations and cars).

Wait so you're saying that it's important to allow predatory business models to continue in the industries that do the most harm through constant consolidation to support ballooning costs?

Like the healthcare system's consolidation and scale that allows it to deal with massive extra costs and the degree to which that system is beholden to predatory technological models is if anything a great motivating example for the potential benefits of a ban

And of course, Joe then foots 2x the bill (denied by insurance, 'natch) when he is brought in to XYZ Healthcare managed hospital for a brain scan
