Adobe just told us the $10 plan is still available…
Adobe contacted us and told us this:
Hi there- Sorry for any misinformation. We haven’t changed the standard 20GB Photography plan, it’s still available here: adobe.ly/2Y5WxT3 or via phone at 1-800-585-0774 We’re just currently testing photography plans with higher levels of storage. ^RR
But I find it odd that they simply have removed this $10 basic plan option from the official Adobe’s pricing page. To me this looks like they are simply trying to do some damage control in the short-term. My bet is soon the $10 option will be gone anyway…
