Yes, your argument was a non sequitur. Just because they were also apparently targeting industrial espionage, it doesn't follow that dissidents weren't "clearly targeted." Both of the Drummond quotes you highlight are completely in line with your subsequent analysis.

Right. Half-truths meaning "these are not lies, yet they aren’t something Drummord is completely comfortable about, either". I'm saying his statements are true, but only a minor part of the whole picture - that this was a much bigger attack, and Chinese dissidents were a minor target.
