It's impossible for any of them to have taken a sufficient snapshot. A snapshot of all unique data on the clearnet would have probably been in the scale of hundreds to thousands of exabytes, which is (apparently) more storage than any single cloud provider.

That's forgetting the prohibitively expensive cost to process all that data for any single model.

The reality is that, like what we've done to the natural world, they're polluting and corrupting the internet without taking a sufficient snapshot — just like the natural world, everything that's lost is lost FOREVER... all in the name of short term profit!
