T2 is doing nothing illegal by doing this; it's a dick move to be sure, but it's perfectly within their legal boundaries to do so. Your rights are not being infringed upon either.
A better legal argument would be that T2 is infringing upon education (however informal it may be), because personally I knew practically nothing about policing when I started playing LSPDFR. After playing for roughly a year and a half, I know how a ton of stuff works; MDTs, ALPRs, I can identify lightbars at a glance for the most part, I've learned a ton about flash patterns and how important they are, a bit of report writing, tactics, procedures, I've learned ten codes, as well as just code itself (code 2, code 3, code 6, etc.) Plus, I've learned a bit of computer handiwork on the side from editing things like Custom Backup and other various meta files and things like that.
Apart from the computer stuff, what I've learned through playing and watching LSPDFR on YouTube will make my life that much easier in the future when I become a cop. I had plans to introduce LSPDFR into my campus' Criminal Justice curriculum for future officers to mess around with, and T2 is stifling that to the best of their ability because their leadership wants to use $100 bills for toilet paper. And that, more than anything else about this whole debacle, is what really pisses me off.
