I am not a lawyer, however this person should definitely hire one. On a cursory reading it appears they need to comply with any discovery requests that match those requested by the California AG's office, which they should already have prepared so its minimal additional effort to comply with, any sort of vexacious requests beyond this can be denied and they could potentially file an anti-SLAPP suit against Amazon as well. The main point though is this guy should not be writing huge Twitter threads where he's making statements that are not precisely accurate (lawsuit vs subpoena) and should hire a qualified attorney to deal with this.
