Adobe sent me this message
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
Still I find it odd they removed the info from their official Adobe’s pricing page. Doesn’t give me much confidence that they will keep the $10 basic plan alive in the long-term….
