This is not the slippery slope you think it is. Grassroots campaigns for industry-wide systemic issues like this will never be useful. It will always, every single time, be a performative gesture that has zero influence on the system structure. This can only ever be solved by institutional reforms, not by a small scale public outcry every week until people naturally forget about it because realistically it doesn't affect them.
As sad as it sounds, it doesn't affect me or anyone around me so I do not care about their issues. And when it starts getting close to affecting me, I will start caring about it.
So don't ask people to join your Johnny Silverhand crusade every month unless something actually major happens such as corporations nearing the point of no return or some sort of existential threats to humanity etc. If that happens, I will happily become Mooda and blow up any building you ask me to blow up. Until then, I do not care.
