It appears to me that it is you who is misunderstanding the comment you quoted. Here is the context:
>> Dr. Hinton, often called “the Godfather of A.I.,” did not sign either of those letters and said he did not want to publicly criticize Google or other companies until he had quit his job.
> As Hinton says in his tweet, this clearly implies that he left to be free to criticize Google.
The comment is saying that Hinton, in his tweet, is saying that the article's statement "he did not want to publicly criticize Google... until" is misleading, and he did not leave in order to criticize Google. This is in fact what he said, and this is what cbolton is saying that he said.
