I could see it being useful for when you want an easy way to get a high voltage spike out of a 5v power supply. For example, if you wanted to build a board for igniting the gas in a potato gun that ran off of a USB power bank.
most power banks don't have the data lines, and as far as I see this device uses the data lines to destroy the host. So I'll guess nothing would happen.
There are some people it will work for. I believe that too.
It is the much larger set of people who see the implications. And who see average Joe bag of doughnuts will already have had plenty of Pepsi impressions, if not Pepsi itself.
Driving some spurious sales with night sky pollution is not something to be rewarded.
I made a chatbot for the website Omegle one time. It just randomly selected messages to send from a list. It was sort of like the emacs psychotherapist but dumber. Some people would talk to it for minutes before skipping.
It would be interesting to actually port the emacs psychotherapist to Javascript or wasm.
Those are not "because it allows us to get more profit." They are arguing that non-free Mathematica is completely in the best interest of their users. Of course it's not. At the end of the day, Sagemath is there for everybody to use and a person can't even use Mathematica unless they're connected to a university. They've sabotaged it with legal barriers and DRM.
