What happens when provider A is bought by provider C and you want to
dump provider C but keep provider B? You'll have created a conflict of
interest for provider B in any negotiation you have with them.

Be aware that provider A's diverse network for provider A's service is
the same diverse network they'll use to connect you to provider B. As
a result, many or most of the outages which impact provider A will
also impact your connectivity to provider B, defeating the central
purpose of having a provider B.
