One super-good thing I did when I signed up for adobe was:
I created a separate email address (purely by co-incidence) that I used exclusively for Adobe (and for some spammy services like some deal sites, which didn't require my card). As a result, I know for sure that my card was compromised because of the Adobe's breach and no one else.
Lessons and observations:
1) I'm glad I bought the CS6. With the cloud comes great risks too. Not to say that you should avoid cloud products, but when you have a version you can own forever, then you might as well go for it. Imagine if I was on CC and my card was hacked and I decided to stop paying Adobe the next month out of frustration. Do you know what will happen? My company will come to a stand-still because I will no longer have access to Photoshop and a huge portion of my company is basically a Media company.
2) Someone else said we're depending too much on Adobe, and I tend to agree. But there is really no superior equivalent for Adobe's Photoshop at the moment. Please don't cite GIMP - I've tried it and it needs a lot of work to even be on par with Photoshop atm. Another factor is the PSD file format which has painfully spread like a Virus and you can't erase it out of your workflow if you're a Media shop like us (Most printing services accept PSDs/TIFF). I sincerely wish why YC companies who generally want to change the world, don't want to create a Photoshop clone/competitor to kill this stupid Adobe that's ruining all of our lives with the stupid CC bundle.
3) The people who really won, like someone else said, were the ones who used pirated versions. I mean, I've paid a total of ~$1400 till now to Adobe and what have I received from Adobe? A 'fuck you' from their CEO in the form of their Creative cloud bundle and a hack that leaked my personal details online making me look like a jack ass to anyone who searches for me by my email. Oh also don't forget the uncounted number of "fuck you's" he's sent me while developing for Flash (on mobile) and Flex.
4) Always create a separate email (or an alias) while signing up for cloud services, so you can eliminate guess work during a crisis. So, instead of signing up with example@gmail.com for Adobe or someone else, use example+adobe@gmail.com (this will redirect to example@gmail.com) or rather create adobe.example@gmail.com or something (gmail is just an example). This way, you can always trace out the right service responsible for the leakage of your details whenever something goes wrong.
I was lucky enough that my bank blocked my card on observing a fraudulent transaction initiated from another country and thus issued me with a new card. I have no plans to upgrade from CS6 or to something else for the next few years. Hopefully GIMP will get better by then, or some YC company will create a better Photoshop and let us own it forever for a one-time fee.
