This might be media drama, and viewership harvesting. But it is still a good and strong way, to treat the costumer support, and address the issues. Something, Asus would not do willingly, ever, until being pressured by billion $$$ fines, which is impossible anyway. Even if this GN move was a bait, it still a win for them, and consumers.
The reason is simple. Once the company got big and the more clients/customers it will get, the more it will avoid resposibility, and to resolve issues. Not really because the can't get rid of all client mass, but because it will eat their margins. It's much easier to set an AI assitant, which will aumatically discard any support requests.
Sadly, there's not movement outside the US. Actually, what GN and other shown in their research and investigation, is just less then 1% horrid, of what these companies and their partner distributors do int many other parts of the world.
GN was flooded with emails regarding RMA issues with ASUS. Doesn't sound like a few to me.
What GN got, is actually the very tip, the edge of an iceberg. The real amount of people addressing issues to the Asus support, and being discarded, might be hundred times more. These are only people, watching their content. There are many other countries, and many other people inside US, who don't even know about GN, but had the issues with Asus products, and did not submit to their database. Most likely many of these people already got burnt hard, and decided to accept the loss, and put the Asus part as past in their lives.
