He is correct.
Ummm. Really ?
I seem to recollect in the heated exchanges when the subscription model was first introduced, and then the 'Photographers' Bundle' was offered to us, that the version of Lightroom included was not configured to run in a ‘subscription’ Creative Cloud mode but in a ‘perpetual license’ mode and would not therefore expire. I may be wrong, but I seem to remember Jeff Schewe saying something to this effect. Tom Hoggarty, Lightroom's Product Manager certainly did. See this URL
Lightroom and the Creative Cloud. This is directly contradicted by Adobe's latest announcement.
The official announcement confirming Lightroom's impermanence, that John Beardsworth refers to, was made only yesterday.
It now seems to be the case that, at least from version 5.5 onwards, that Lightroom is now in subscription Creative Cloud mode and will therefore expire if you do not keep up your subscription payments. Whilst I laud the decision to keep all the modules working with the exception of Develop and Maps this does mean a change of the terms of the original contract which in the UK, at least, would be ruled unlawful. The original terms would still have to apply over the duration of the original contract.
Sadly, this double talking contradictory nonsense does nothing to enhance Adobe’s repuation.
