I think the point is that the Fediverse is severely limited by this vulnerability. It's not supposed to solve that specific problem, but that problem might need to be addressed if we want the Fediverse to be able to do what we want it to do (put the power back in the hands of the users)
That first one is pretty good. If you had asked me what 550/2 is, I'd have said 275. But since you showed me 225 before I thought about it, it confused me.
