I need to read more of the court case, did he just create a ton of free accounts? If that’s the case, then he shouldn’t be charged with anything because the worst crime he has committed is breaching TOS. Don’t they have arbitration clauses in those?

After reading a bit more it appears he social engineered away some of the limits AWS and Microsoft impose on new customers and just never paid his bills, regardless of how high the bills are. This still seems like a civil case, not a criminal case. If he stole money from a bank, criminal case. But he stole usage from two corporate entities by never paying for the usage. Imagine getting dragged into a criminal case for not paying your telephone bill.
