#5 is also pretty weak. It's just a link to a post where someone is complaining that the admins won't remove some free speech that they disagree with.
You can't just call people bigots because they are enforcing certain rules. The admins aren't the ones posting the content.
Plus, overall reddit interaction has barely gone down. Daily visits went from 55 million to 52. That's a drop in the bucket.
One thing I learned a long time ago is that internet people just don't give a shit about doing what is right, only doing what is easy.
So yes, spreading news about Lemmy is more important than trying to take down reddit by not posting.
