They're a loud minority because they've invested more into the platform. It is the 1–9–90 rule in action.

When the 1% leaves the platform's quality will go down.

My bet is that quality will go up. I'm not really interested in reading what the small number of people who spend 8+ hours per day on Reddit think, about any topic. Hopefully they'll take their silly Reddit mannerisms and inside jokes with themselves on the way out.

Unfortunately I believe the ones with the Reddit mannerisms and overused jokes are the ones that stayed as they are too addicted to leave.

The actual creators of content are different from the drones.

We'll see. Reddit will not die in 2 weeks that's for sure. But some people will leave and maybe a viable alternative will surface as a result of this shifty behavior
