You’re not wrong that modern advertising works like that. In my case I haven’t shown these anywhere and just got my first batch in yesterday and was so happy with them I wanted people who would actually appreciate the comment to see. No links. No cart. Just “I’m proud of this”. If someone went and bought some hex stickers from RedBubble after seeing this, good. If they found mine, good on them for tracking them down. On the FOSS chain of thought, I think, at least for the FOSS stickers, these should be on GitHub or a self hosted web server as whatever creative commons means don’t sell my files/prints. That would take a day to spin up and might let people print them themselves if they’re so inclined.
