Exactly.  Which leads me to believe that speedfactory uses 205.152.37.254
(one  of BS's main DNS servers) as to refer your query to when it misses
it their hosted sites or caches..  So, when you hit speedfactory's DNS and
the query fails there, it's by default referred to BS's server.

The only time you're likely to see these entries are when you're on a
network that's in some way served by BS's DNS, as these particular DNS
servers are only used for BS ISP customers and access is pretty much
denied to anyone else.  So, indirectly, you're still using BS for quite a
bit, however you might hate that ;-).
