Sadly it seems most users just go where the critical mass is. They don't see to care the people earning money from it are pieces of shit. They just are where everyone else is. Now, what makes people leave a community in mass, I don't know. Human dynamics are strange.
Most people just want to use something without thinking about it. We all have lives to live. I will not give reddit anymore of my time and I wish everyone on reddit and the fediverse well.
