How so?
If carefully chosen, each service provide something unique.
For instance I have Netflix and must keep it. Netflix is very expensive and must change or lose out
I have Acorn and Britbox. Each provides a host of different programing from the UK, Australia, New Zealand and Canada. I recently signed up for PBS for certain Masterpiece programs.
We especially like Australian programing
The older programs are very good. The new UK programing features black characters in 18th century positions of prominence that make it just ridiculous. They have jumped off a cliff using negro actors in all sorts of inappropriate roles
