Without knowing the particulars, that's an interesting example. The fact that Miku was going bankrupt suggests that they did not have a viable/sustainable business, and perhaps they could have been profitable with a different (i.e. subscription fees) business model. In either case, new company seems like they do not much value existing Miku customers, as demanding more money for a product that was bought/paid seems pretty outrageous.
They pushed out an over the air update the bricked nearly every device and had to swap them all out right before sending out a letter warning they were going to file.
The lesson that it drives home to me is that if a company can force updates to your device, it doesn’t matter what the terms of service are or how much you trust the company.
They can go bankrupt, sell off the assets, and some new vampire company can come along and remove your ability to use your product.
