Compare to food: it's like demanding that Walmart screen all the food itself to protect you and then you'd screech at Walmart and only Walmart for not making sure Keloggs cereal is healthy while letting the manufacturer off the hook with zero (I repeat, zero, none, null, NADA) consequences for fraud and damage they caused.
The way media, HNers and other people behave is creating a situation that's terrible to the extreme.
Now, do a thinking experiment: how did we ensure product quality in food/electronics/other parts that DID NOT hang on the fact that Walmart has 100% monopoly on all sales of those products and completely locks out you ability to go to any other store? How did we build a system that holds manufacturer of fradulent good accountable, not the megacorporation doing the distribution?
