Paramount Network UK is taking 5Spike's EPG place on multiple platforms, including Freeview, as 5Spike closes.
The video on the tweets shows content of the type that is currently on 5Spike, so I would interpret that as a merger of the channels.

Looks like a cost cutting measure as there is no indication that anything is happening to the 5Spike space i.e. for a new channel.
There isn't a Spike brand in US anymore, it closed over a year ago and was replaced by a completely different type of channel as I recall.
