What is a Roku? Some sort of feral animal that has gotten out of control.
I don't know about you, but that divergence in volume and accumulation/distribution sure looks like most people don't want to baghold Rokus and are releasing more of them back into the wild as their price goes up. The Danish government slaughtered millions of minks and minks are cool and have a clear purpose for warm coats. Rokus don't. Why have a Roku if you can have a Netflix and a Disney+ on your laptop?
Short the Rokus.
