Until then, I like "protect". :)
Very few mottos can withstand literal dissection. For that matter, many phrases have entirely different meanings than if they were read as normal words.
Words bend to the context, and by associating a motto with the ideal it is proposed for, it quickly becomes its own context.
"Protect the user, their data and the truth!", if you say it loudly, comes across to me like something the Three Musketeers would exclaim. If they were programmers, about to enter the forest of dark patterns, risking their lives for the users they know, and those they will never meet.
Love it. All subjective of course.
