So you currently subscribe to everything available on Lemmy? Reddit? Facebook? Twitter?
If that answer is no and you don't view every discussion you already subscribe to exactly what I am stating. A few things are going to happen in this community, it will happen again and again and has happened before. There will be a difference in opinion and people who choose not to be a part of the community will move on to another community, platform, etc. to find the niche where they fit and help to shape it.
The choice right now is the shaping of this communities future. At the same time someone is not going to be happy about the direction, allowing discussions to continue in another community is a good way to help the current community thrive with minimal conflict while focusing on a niche. By taking a particular conversation to another community will allow community participants who want to explore another aspect to do so freely without taking topics out of this communities niche. It will then become another thread that connects us all in its own unique fashion.
