The Adobe Creative Cloud is poorly engineered. It's a hacky mess of like 20 different processes, an embedded node, it contacts like 20 different domains... what a total hackjob. I bet they just cobbled this stupid shit together without really planning it well, then put some code monkey to smashing all the obvious UX flow bugs until it was deemed "polished" and shoved it out the door
That's how most software is made at this point. By committee! Usually of Redditors and H-1Bs.
