Can you or someone else with more business tech knowledge explain this to me... historically, we have seen companies with patented or controlled environments open up their tech to various levels and see overwhelming success. Fuck-you-money levels of success. While I do understand wanting to keep a tech patent a little close to the chest, a tech patent seems to generate Scrouge Mcduck money when they hug as many devs as possible. Why do we still see this ass backwards patent holding? 30% of millions/billions of small berry pies is far better than 99% of one medium sized cow pie. Any good reason why Eink is that way? Just plain stupid or is there a good reason?
