“Just” leaking full source could be enough to destroy a lot of IP-based companies. A lot of companies stay wealthy because their IP is so huge than nobody can afford to develop competitive alternatives anymore (Adobe, Microsoft Office, Salesforce etc). Some of them have actual “secret sauce” that they cannot afford to share (suggestion engines, biotech processes etc). Even a service like Github, which relies on others entrusting their work to them, would take a humongous reputation hit from a leak like that.

I don't think either of those companies would cease to exist if their code bases leaked online today. Sure, someone might get something to build, but there is surely A LOT of things around the code bases to support all of this, which means the code bases would mostly serve as a study for software in general (and finding holes obviously).

Github is a bit unfair comparision, as their business is literally to make your code private, so if it leaks then of course it would be a hard hit. For the general company, I think leaking access credentials is a much bigger (but easier to fix) problem than leaking the source code itself.

A serious Photoshop clone that can match PS feature for feature would wipe Adobe, people cannot wait to get rid of them. 25% of MS revenues comes directly from Office and another 25% from Windows or other commercial offerings that are basically driven by Office, so yeah, MS would survive a working Office clone, but they would be deeply wounded; they pulled all the dirty tricks in the book to keep competitors from integrating seamlessly... having the real code responsible for their formats available in the open, would hurt them massively.

These companies are as big as they are because they did the right moves at the right time, and now they have spent so many man-decades on their codebases that nobody can realistically hope to catch up starting from scratch; but having a good look at their codebases would likely kickstart oozes of competitors with very good chances to replace them in a very short time.

Credentials are a mean to an end: protecting something. If you are Ashley Madison, your valuable IP is your database of users and their preferences; but if you are Microsoft or Adobe, what credentials are protecting is your source code. Adobe survived their user credentials being leaked, like so many other companies. They would have hurt much more had they leaked the entire PS codebase.

But a competing company can't just give a copy of the leaked source code to their developers and tell them to go to town. Even by employing clean room design, you can't get around all the patents that likely protect many of the features that Photoshop users consider crucial.

Just open a shop in China and obfuscate a bit. Job done.
