I’m not sure I’m understanding the point of your comment. It sounds like you are making the case that somehow Ublock origin announcing they are no longer blocking ads on facebook because it’s too cumbersome, somehow will not cause companies to be like “oh facebook figured out the ad blocking problem, what did they do” and then try to implement similar systems.
Yes more people could contribute, but you know what else would help the cause as well? Not announcing to the world the solution to break your product. They have now put in writing that the solution to making the “problem” their product creates go away, is to just make it super obnoxious/tedious for the team to try and find filters on. This is going to act like gas on fire and only cause more work for them than if they had just silently let the filters phase out and use the excuse none of the maintainers are on the platform anymore.
