This is news? To anyone?

Of course they are a waste of money, and the plastic packaging is incredibly bad for the environment. And they are fun and I will buy them again next year.

Unless I’m mistaken, and I probably am, the patents on blueray should have expired by now. Software side might be covered under copyright right though. Not sure if software can be copyrighted though tbh.

Didn’t know that. Thanks!

134a is for automotive ac units. Unless something has changed recently, household hvac systems use a different type. It used to be R22 for both, but that was a long time ago. Turned out freon (R22) was bad for the environment.
