Dont forget that this is not a boycott and that as of right now, "not crossing the picket line" mainly refers to those within the industry not writing for, going into talks, or making deals with the companies that fall under the AMPTP (Alliance of Motion Picture and Television Producers, representing pretty much every large production company under the sun). As of right now there is no official boycott or call to cancel subscriptions. Boycotts on a large scale, unless officially called for, could do damage to the strike, whether through harming potential negotiations or preventing pay for striking workers through residuals and the like from projects that they've already worked on.
The best support for the strike right now will mainly come from social pressure on the AMPTP, and the official website (wgacontract2023.org) has a social media toolkit that includes info graphics, icons, and other material that can be posted online. There is also potential good to be done with monetary/mutual aid support in cities with a strong entertainment industry. The wga website has links to funds to help with financial aid for union members. Another post mentioned looking out for suggestions or news from local chapters of IATSE and Teamsters, which is a pretty great suggestion.
That said, I also think that as the strike goes on, this is a great time to seek out more indie entertainment. Tubi seems like sort of a haven for indie films right now, and my suggestion is always to look for titles you've never heard of just to give them a go. I promise you'll have fun!
Remember to support the strike, but also that the goal is to not have to strike! This is going to be a hard time for industry workers, but they're doing it for the good of the industry as a whole.
(Dating this on 5/3/2023. Look to the wga website for the most current news on the strike).
Edit: I originally wrote the MPAA instead of the AMPTP, whoops.
