looks like the main contradictions are in terms of the scope of the google project (300 employees, full time), the amount the project has been developed already (a very substantial amount), and the awareness of political issues as demonstrated by the leading google employees on the project (more than enough to know they're doing the wrong thing).

it also appears as though they are fully conscious of the prospect of social censure:

>We are working with you to make sure your careers are not affected by this.

so, they know they're clandestinely doing immoral things. but google corporate is determined to protect the minions from the consequences of being identified as an aid to totalitarianism.

given that we don't have a list of the google employees working on dragonfly, i think he's just succeeded in tainting the reputation of 100% of googlers and former googlers.

any one of them could have been working to keep the chinese oppressed via censorship by knowingly joining a new project designed explicitly to do so.
