I think the publishers get a lot of stick, much undeserved.
members of the forum complain that they are changing digital access, while openly discussing how to make and share electronic copies of the magazine! They should get some credit for not deleting every thread or post that is either critical of them or discusses ripping pdfs of magazines or suppressing advertising- though this may be more the tolerance of our editors than that of our publishers! That said, healthy debate is what keeps people engaged.
I don't pretend they have chosen the best or fairest solution, but e-publishing is still a new field, and the publishers must be looking at what they have got and wondering how they can make an ongoing return on their investment…
I agree with Stephen that making this website as popular as possible and using that popularity to support advertising makes sense. The links to the magazine are a critical element of the health of the website, at least over he next 20 years, and I don't envy them the task of finding the right path.
