Not entirely sure what your argument was here, you sort of drifted into the weeds a bit.
I think you meant to argue:
"There is one source of media coverage, although it's largely just twitter comments. And just because something is difficult to prove doesn't mean it's not provable."
Both are valid arguments.
I don't count ZDnet as a very credible source of news, and in this case, some googling seems to show they are practically the only "news site" running this story. Although, as pointed out, it's mostly just a paragraph followed by several twitter posts.
Secondly, the evidence thing is important if a case like this were to proceed. In order to sign onto the class action, you would have to prove you purchased an effected chip/board, and that this driver is what killed your product.
Two problems here:
1) You bought a counterfeit chip/board. It's unlikely any award will be levied for illegal/infringing products.
2) Users would have to show evidence they were effected. Even in the RedBull class action case that is settling now, you must prove you bought a RedBull during the time period the case covers (receipt or whatever). Again, you have a counterfeit product, which was illegal to sell/buy in the first place. Not to mention, getting average-joe to test his device, even if someone made a testing utility and freely distributed it, will be close to impossible. People who are technical and care may do it, but average-joe will assume his arduino went belly-up one day, and likely toss it in the garbage.
Let's be realistic. A handful of people in-the-know will care passionately, and do everything they can to further a claim. Several handfuls of people will care enough to do something if they believe they will get something in return (a payout). The rest will have no clue this is even a thing, and will simply throw away their "defective" device.
What FTI did was wrong. But there is no real recourse here.
