In my case I disagree..it wasn't ours to begin with...we didn't "create" as your article states...it belonged to another bakery or whoever created it from the google page they got it from. How can my ex-employer say it's "THEIRS" when it wasn't THEIRS to begin with. THEY stole it basically from another decorator. Capiche?
I understand what you're saying -- we get that kind of thing at work all the time too.
If a customer pulls something off Google that has a copyright, we're forbidden to do it because of the legal implications. If they want a copyrighted design, they can choose an image from our edible image book. We won't copy anything from another bakery. It's considered unethical.
BUT...as long as you're making that particular cake at your place of employment, the cake itself, not the design, belongs to your employer.
