I'm very curious to all the ad proposals and how it will look like!
I also would like to mention the situation / context is different in Brasil than in here (The Netherlands) were the billboard is currenty running (only for the coming week). My goal with the ad here was just to create an example how we could grow curiosity. The people here don't have a problem of platforms being banned (not yet...) and seeing their voice / reach taken away from them. I think the data portability of your own data is something will resonate much more among the people here for example. In Brasil there are different problems with more urgency I think.
