Pushing a banner to all phones with a political message would be a brazen abuse of one's engineering position. This developer's change was much more narrow, it modified an internal tool that only Google employees see. But it's still breaching professionalism. If the message instead was, "Unions are corrupt and deprive people of individual agency" would that be acceptable? Especially with the unique position Google is in as our gateway to information, it's prudent to avoid employees that cannot refrain from making changes to production software to further personal politics.
