>So on any price increase that you know a loophole for to avoid.
Well, obviously he/others/i do? I do not see this as any problem, it is nothing forbidden or 'wrong'.
Hell, if RIPE charges me per size for legacy i can pay it as PI, if they do it for PI or increase PI fees insanely... it's still mine, it might end up with APNIC or "DB fixed" unchangeable but free/lower cost (and everyone else that has no choice to move will be punished).
You seem to understand how the process works within RIPE, but this will ultimately just end as above, our loophole is not really fixable (i think we now all know "taking legacy IPs away" is theft de-jure, right?).
