Sorry, this is not a "blog post" - it's far closer to digital marketing. A lead attractor as the author is trying to sell a service very clearly by the end of his page (no disrespect meant to either).
Heavily depends on the contract with your ISP, I'm not aware of anything saying you can't use your uplink "commercially" - how one would even define and monitor that?
I don't think in this case that most people who know what Arduino is would be at all mislead by the title. Being "dead" doesn't have to mean that a company ceases to exist. There are plenty of what I would call "dead" companies that still make money every year. "Dead" can be used figuratively. In this case, meaning that though the company continues to exist, the reason for which many people bought their products is now gone.
Yes, you may consider that opensource models hosted over Openrouter are charging about bare hardware costs, where in practice some providers there may run on subsidized hardware even, so there is money to be made.
So you're suggesting a denial of service? I doubt the sandbox is running on cooperative scheduling. Ultimately the VM can be run for some cycles, enough to get work done, but enough to permit other programs to run, and if the decoder doesn't seem to be making any progress the user or automated process can terminate it. Something like this already happens when js code takes up too much time on a browser and a little pop-down shows to let you stop it.
You can if you bound the program in time and space. In particular if you put a timeout on a computation you know for a fact it will halt at some point before the timeout.
