If this graph were true wouldn't we be seeing attacks all the time? If coins could be exploited for just hundreds of dollars they'd be rendered useless pretty quickly. This can't possibly be accurate.
Here's the next line from your [1] link that's pretty crazy as well.
"They conclude that "release of up to 50 Gt of predicted amount of hydrate storage [is] highly possible for abrupt release at any time". That would increase the methane content of the planet's atmosphere by a factor of twelve"
Around Mid 2013 Bitcoin supply was around 11.5M coins so 630K was more like 5.5% of total Bitcoin. Just using a different kind of math. There's more coins now so using todays market cap % makes it seem less then it actually was.
The webhooks are important because stripe doesn't email you about failed payments you need to do that on your own.
And the default for a 3 time failed subscription over a 15 day period is to remove the subscription which you can easily change to keeping it but labeling it unpaid among other things.
Especially when you're telling them they only need to work 6 hours. If my boss said we're moving to 6 hours a day, I'll be pretty happy to oblige and be in when they need me.
That's their official response, and rightly so it should be. Talking from experience, I've had many requests for different websites I run and almost all were frivolous. Some content I took down anyways, and some I explained to Amazon why it was frivolous. They've never cancelled any of my services or even threatened to.
Amazon's not in the business of terminating accounts the second a copyright request comes in. They want to build trust with their customers that they won't just turn you off on a whim.
