I'm ok with subscriptions as long as I get to keep the latest version forever. I'm not ok with being locked out of my work when I can no longer pay for the subscription.
Now if I'm working for someone else, then sure! But, say, an author, who can no longer edit their old works for a republication? Not a chance.
