It's childish in that if they did go to court, the company has a stronger case against OP as he publicly named/shamed them. Often in such a case, the company even becomes the victim!
I agree with this. All of the comments about a potential claim OP has against the company assume that he was actually an employee. Perhaps OP can elaborate as to whether he was an employee or not? If he was an independent contractor, then it's a completely different story. Also, by publicly shaming the company, OP also opens himself up for a defamation lawsuit.
