Reddit is not actually in scope for the strike (more detail here https://www.rebeltechalliance.org/collectiveaction.html#attention-strike ) but i see what you mean.

Sure, people in this community will be way beyond this. The idea is to share it with your friends and family who are not there yet. I'll tell Take Back Big Tech that the next strike would need to be much more significant. This one is supposed to get people used to the idea, and to try alternatives.
