Calling companies that hold a patent you find valuable and aren't distributing it's use how you personally see fit a "patent troll" isn't just inaccurate, it's an intentional mischaracterization for the purpose of eliciting a negative emotional response solely to spread your narrative. It cheapens the meaning and lowers any engagement to fight for the same cause when you realize it's a facade driven entirely by sour grapes and a lack of understanding of the patent system being criticized.

I guess it's okay here though, because [passionate story about side project idea using eink that could be tinkered on but never actually idealized into something].

That's bullshit though. People always make this claim but never with evidence or a source, or they provide a source that has either been retracted or simply states the same claim without evidence or citation.

That is essentially the entire idea behind patents. They get a limited time of control, the public benefits later. Like it or not, this is how the system is supposed to work.
