Adobe recently chose to stop the Extract tool from Adobe Assets in Adobe Cloud. The result is that developers now have only two solutions : 

1. Use another tool (Avocode, Zeppelin, Sympli, etc..) : all of those products have some restrictions that will make devs be less productive, 
2. BUY a FULL photoshop licence : this feels to devs like a hold-up. 

@Adobe : it is still time to change your mind and maintain Extract. Some proposed you to pay for this service but your response is copy and pasted on all your posts. Seems we are talking to a bot. 

Please all devs sign this : we still can make Adobe change their decision.
