This one's fine. Your beef here is against the FDA rather than ArsTechnica.

The main issue I'm bringing up here isn't that the titles are misleading (though that's obviously a problem with the first two), it's that even so-called technology news is little more than political propaganda at this point and often has little to nothing to do with technology.

Unless Ted Cruz's statement is a fabrication, they are right to call him out on this. I've got a more charitable view of Proof of Research since the makework that "secures" the currency is only useless to the miner and not to civilisation as a whole, but neither does anything good for the electric grid.

Ted Cruz's idea is to use Bitcoin mining to help pay for excess capacity when that capacity is not needed elsewhere so that when that capacity is needed the mining operations can be shut down.

I don't think Ars Technica is wrong about Cruz's plan not being practical, and this is actually technology news, but it's hard to be charitable when it's one of 4+ articles on their front page attacking conservatives.
