You are correct - that I agree with. If we define degrade as losing some ability of the chip as a one time event, then yep, a delidded chip often seems to no longer reach the same high OC with extreme cooling like LN2. That can be a bummer for those few who want their cpu to be able to do that.
But the other type of degrade definition of having a delidded chip start to need higher voltage to reach the same OCs over time with air/water does not seem to be a problem. I think a delidded chip is less likely to degrade this second way and will probably last longer then a lidded cpu when run at 4.5-5+GHz on air/water. And I think that is the more common and likely way to define degrading a cpu. IMHO.
