Who said they are not letting the site stay online?
I was involved with some sites recently that stopped publishing new content. The plan is to keep most of it around for now. But I have no illusions that if it becomes a "project" for some reason or another in a few years, it will just be turned off.
If I stop posting new content, have I stopped publishing? Or is it if I stop serving, then I've stopped publishing?
Saying “we will no longer publish content” could very well mean they are taking down the site; thus it is no longer published
I think it’s very likely that this is what’s going to happen because even a static archive site is going to cost money and dilute their new social brand
Perhaps they’ll repost their old stuff on their new channels but it will nevertheless suck for old timers like me that refuse to use social media
