With news that Threads has reached 175 MAUs, this is an interesting waypoint in its life worth keeping an eye on.
Currently, Thread is an ad-free and watered-down attempt at building a Twitter replacement, but that is about change when Meta decides to turn on ads, as they have alluded to in recent interviews with the tech press.
This will only incentivise the worst behaviour from both Meta and its real customers, the advertisers. The enshitiffication cycle has started.
Watch carefully and you will see it unfold in clarity.
