Yeah. People get themselves over on Twitch for thousands of different reasons; about the only thing that’s needed is an ability to connect with an audience, something that 90% of pro wrestlers learn to do as a necessity of their job. That's a skill they possess, not a company asset provided exclusively by WWE; if they advertise for their twitch as “(Trademarked WWE Name)” and staying in character, that's an issue, but if all that WWE did was get the real person some popularity… that’s not WWE’s asset anymore.
And the vast majority of the talent doing Twitch weren’t in character, and we know for a fact they weren’t being forced to read the crap scripts from Vince, or consulting road agents to plan out their gaming strategies, or cooperating the figure who was going over or anything like that.
According to WWE, they’re “independent contractors” who don't require company-supplied health insurance, and yet can’t accept other dates and paydays from other programs, and apparently can’t sublimate their income in stuff like Twitch without setting off WWE’s freak-out meter. If they’re not going to let them be “independent” even outside their industry, then they should be paying some damn health insurance.
