Just a quick comment on advertising revenue. It is a known vector of malign propaganda, and laundry for funding provided by bad actors. This is evident from the deliberate destruction of profitability of media dependent on advertising revenue, such as news, late night TV, and similar venues, as well as the self-destructive banning and censoring of big social media sites that is contrary to investor interests.
Actual capitalist investment intent on emuneration isn't the main incentive for advertisers, and the targeting of funds for seemingly suicidal platforms and channels demonstrates this. Were @dtube to become dependent on advertising for any substantial funding, it would become captive to these machinations, and there's no point to undertaking advertising models for funding that isn't substantial, particularly given the blowback that would engender.
Thanks!
