That dude's story yesterday concluded with switching from one $5/mo/unlimited provider to another. I'm guessing we'll see a post from him in another year bitching about Crashplan and then maybe he'll realize that $5/mo is too low a price to pay for an unlimited amount of data to backup reliably.
I agree. If he's only willing to pay $5 per month, the data can't be worth THAT much to him. I don't think it casts a "serious shadow" on anything. Backblaze seems like an awesome customer-focused company.
