Mmmh, you could be right there.
Ok, but you have still the other competitors. And even if you count them out, there will always be instances that federate with Threads. That's how the Fediverse works. Yes you can do coordinated actions, but only to a point. For letting Threads enshitificate, you would need an air-tight wall from Threads to all other instances and that's not possible.
Ok, so we have come to a conclusion here. That's fine. What I'm not sure about is whether these two standpoints will complement each other in some way or work against each other in the future.
I at least will take some interesting points away from this.
