You have the right to disagree. Absolutely, no problem.
I did read your post but you haven't really read mine. I'm not saying that paying for 10 years includes new user adoption but at least provides some insurance that what is currently there remains there and doesn't impact current users of any platform because the information is still there. I don't find the 10 years as a small amount of time. At the rate things are advancing I'm quite sure solutions will soon include all the post information (including images) directly into the blockchain and have them there forever. Or any other solution. 10 years is a long time in which innovation is sure to happen and tbf, in 10 years, I think we'll look at this post and laugh of its stone-age style.

What I do feel to emphasize is that the devs need to be creative and provide some sort of assurance that encourages users to use the platforms and assure them that we are in for the long run. Each dev's resume is one thing to be considered and I also happen to suggest a 10 year commitment for the minimum functionality to be available as ensured. Is that too small? Is that enough? I don't know. But it's 10 years where your posts (int his case) will have their images listed. If anything happens down the road it would be plenty of time to think about backup solutions or maybe those 10 year old posts won' matter anymore.

I really don't want to turn this into a contradictory discussion. I respect your position but I also think what I'm saying is feasible.
