Unilateral changes with little or no notice
You are agreeing to accept updated terms solely through passive continued use of the services.
“Your continued use of the Services after such updates become effective means you accept and agree to the updated Terms.”
What that means: You lose the ability to negotiate new terms and may be bound by unfavorable changes without knowing.
Adobe can change the terms unilaterally and binds you to them simply if you keep using the service, with no requirement for active re-consent.
