I agree with these posts. From the UK, the J-Up is long gone but we have P/Z fares anyway which will be as affected.
This will affect LX badly, they wouldn't have these offers if they didn't have difficulties filling their premium cabins. Let's not forget that the network carriers have a terrible problem squeezing some yield out of European flights.
I never once upgraded an OS flight despite getting the offer every time on OLCI, I am sure many other Elite's did the same thing given no miles, look at the state of OS. (Not suggesting that there is a major loss of revenue from not offering miles for paid upgrades online )
