Now for the followup question:
Will these ads be in the form of namedropping corporations and products as the "official government sponsor/provider/service" or will it be in the form of an ever-changing constitution that due to its ephemeral nature can only exist digitally and will require a 30-second ad to access?
The most logical approach I can think of would be starting up an instance, flooding it with bots, and using those bots to spread to other instances.
However I don't use Lemmy super often but from what I understand intance admins can block other instances so it wouldn't kill Lemmy entirely, it would just make it worse to use, which is a detriment because the most-cited reason I see for not getting involved in fediverse apps seems to be the learning curve upon entry. Open instances would be flooded with bots and all actively maintained instances would need to start isolating themselves from other instances and heavily screen who gets in
