I don't know how fatal this will be for Samsung next time they go out and sell phones; but people have got a taste of buying from a company that doesn't have any sales or customer rep centers easily accessible where people can go and complaint. I really hope it doesn't turn out to be fatal for them but I also hope it breaks the Samsung monopoly over Android and let brands like LG, HTC shine.
I have a Nexus S (Samsung), a Nexus 4 (LG), and a Nexus 5 (LG again). As you might guess, I bought those without really bothering to consider who the manufacturer was.
The 5, the most recent one, has failed catastrophically and eaten my data. The 4 is suffering from a swelling battery, and will be thrown away as soon as my OnePlus 3 arrives.
The S, two years older than the 4, is still going strong, although it doesn't seem quite up to the demands of modern android software.
To the extent that a "Samsung monopoly" exists, it's not at all clear to me that breaking it would improve anything.
