Fist: Yes. “Where do I find the ambassadors in an event? Please reach out to the ambassadors on their social media if you have trouble locating them at events.
As an event attendee, what can I get from meeting an ambassador? You can get your questions answered, share your feedback, and get Framework stickers and other goodies. In case you haven’t before, you will also get to see a Framework Laptop in person.”
It’s written down black on white: ambassadors need to be available on social media to schedule a meeting, reply to questions, and hand out “stickers and other goodies” (=those aren’t even for the ambassadors to keep).
Second: so there are, by your own admission, requirements tied to getting some stickers.
That’s a job. It’s not a full time job but it most certainly is a job.
