- Never walk away from a former employer with code on your computer. - Never walk away with an employer's property. - Never walk away with a functioning email account. - Never walk away with documents. - Never walk away with paper. - Never walk away with anything. - Just walk away.
That's not up to the employee, though, but the company's IT. More like - Ask them to shut down your email account, tell them you'll stop using it, and never use it again?
Ditto for VPN and any other access to their resources aside from strictly limited access of their public facing web site.
A great example is not removing you from cloud services - this makes them look bad but also makes you look capable of theft. It's more important that it remain possible you committed theft than not. Another is if you used a personal computer for work, as most people I know in startups do these days. If they won't supervise a deletion of the code off your computer YOU CAN NOT DELETE IT! If you are sued, you've now deleted things - what if you turn out to be the only person who had it? That's the real theft, and this has come up in real life cases I've seen - it became critical that the code WASN'T deleted.
The statement to never leave with code, email accounts, etc. is just not practical. It requires cooperation from your employer that will not exist in a situation where they're planning to try to bury you in litigation. It's a fools errand to try to pretend like there are reasonable steps the defendants should have taken - they took many reasonable steps and the plaintiffs can always find more that should have been taken.
One more trick you can do, although I doubt it will help much in such a bad faith situation---but maybe do it with your lawyer for documentation---is to change your passwords to randomly generated ones that you don't retain. E.g. run pwgen and cut and paste the password into the change and confirmation fields. If with a lawyer or notary, put them in front of the screen at the right point and have them generate the new password and enter it in, and document that you didn't and couldn't see it.
And that will remove all temptation to touch the forbidden fruit. I've done that with a few forums where I really didn't want to continue joining in the ... discussions.
As a side note: everyone saying categorical things like "never walk away from a former employer with code on your computer" - remember that they don't know what they're talking about. Categorical statements in these situations are never correct. This is about a life lived honestly and in good faith being turned around on you - don't feel like you did anything wrong, just take opportunities to learn.
Lastly, to everyone giving Smule the benefit of the doubt remember: this means nothing (NOTHING) to Smule and everything to the Shred Founders. If Smule turns out to be right (which seems ridiculously unlikely), then it still means nothing to them. If they are wrong, which seems to be the case, they're destroying a company and lives at the same time. Keep the stakes in mind when you're considering the situation.
