IIUC, that's always a good theory for unexplained DDoS. Though, even if they have only profit motivations, I'm a little surprised when they don't seem to let ideology influence their selection of targets for demos.

For the sake of argument (maybe not true), let's say that all techies are aware of archive.org, and consider it beneficial, probably using it themselves.

Why don't they instead demo against a target that will be proof of capability, and one that someone won't pay them to do (no freebies), yet one that they perceive as bad or deserving in some way?

Probably improper to suggest "better" targets here, but I really wonder what's going on when some relative do-gooder gets attacked.

Similarly, ransomware attack on a children's hospital, of all places? Doesn't that get you uninvited to criminal mastermind dinner parties?

As Omar of "The Wire" told us, a man's gotta have a code.
