Say a company stole intellectual property from an employee(accept this as fact pretend he understands the contracts he signed and that this was infact his IP) . This employee is now concerned since the intellectual property was brought to the company it seems as though they are developing it themselves and disregarding the employees pleas to not steal the intellectual property.
A lawsuit would most likely be lost as the company has a large amount of resources to either win the lawsuit or drag it out.
The employee decides to exercise his 1st amendment rights. He decides to comment on all LinkedIn post and Glassdoor reviews informing others of the companies bad practices. He registers a domain and begins to comment on all their posts saying CompanyXIntillectualPropertyTheft.com and CompanXLiars.com where he plans to detail all the companies misdoings in a factual way.
Is what the employee planning on doing wrong or in any way illegal?
