The allegation you quote
is not an espionage allegation. It's saying that because this activist's Twitter account received unfavorable treatment from Twitter, we should assume that the unfavorable treatment of his account is evidence that Twitter is an arm of the Saudi government, and therefore the separate incident involving espionage must have happened with Twitter's cooperation or at least without Twitter's objection.
Note that the quoted allegation does not even allege any misconduct on Twitter's part! The only purpose is to ask you to draw an adverse inference about what Twitter was thinking when they became the victim of espionage.
