The reason why SAG and the WGA got such strong support is that they largely used social media to build up support. Folk like Adam Conniver were actively doing the rounds on a LOT of media (and gaming) podcasts to explain what was going on and why the gang were going to play KOTOR instead of continuing to watch Star Wars and so forth. And I am sure stuff like the Always Sunny podcast and Scrubs re-watch had similar messages from the actors who hosted it. Which is in stark contrast to the last round where it was “Well, Lost and Breaking Bad are never coming back”
For the auto workers? I wonder how much of that is support versus apathy and general disdain for c-suites. Like, I support the auto workers. I also am under no illusions that their strike has any meaningful impact on me since I am not buying a new car until at least next year (when the EVs I want are native NACS and have rear window wipers).
