Exponential??? They sold in huge numbers. Some units are having meltdowns. The vast majority are not. The tech press is just highly focused on any story and thus making mountains out of molehills. In other news:
- sharks are not biting every person that goes in the oceans
- hurricanes are not completely destroying every house and every community their wind & raindrops touch
- floods are not destroying every home in America
- every Clinton email ever written was not corruption waiting to be exposed
- every Trump action is not driving us toward nuclear annihilation
- every athlete is not refusing to respect a patriotic custom
A small number of Samsung phones are indeed melting down. The vast majority of them are not. There's enough of an issue to motivate Samsung to recall them all and fix the issue, rather than- say- trying to deflect with a variation of "you're holding it wrong." Do they have a component problem to address? Yes. But don't we all know if this was Apple's problem, we'd be spinning it as user error and every other possibility to deflect blame from the Almighty? No particular love for Samsung on my part... more of a "get real" rebuttal here.
And none of the above is in an exponential rate expansion- just hot news of the moment getting as much attention as can be mustered... until something that draws more eyeballs comes onto the stage.
