Lemmy as a social media discussion forum is about human attention. The economy of success on lemmy is curating a audience and having their attention both in terms of voting, but more importantly, in terms of discussions.

Competition between communities is healthy and good

• Better content
• Better curation
• Better community (welcoming, etc)

Trying to "boycott" or starve out other communities by making them "redundant" by burning out human attention on lemmy is bad for everyone

• Lemmy feels empty
• Repetition of content is wasting people's time
• Dividing the conversation drives people away

If you hate a community, make a better community, don't try to burn out everyone who likes the old community.
