I believe that a good reason not to wish your node to be segwit compliant
is to avoid having to deal with the extra bandwidth that segwit could
require.   Running a 0.14.2 node means being ok with >1MB blocks, in case
segwit is activated and widely used. Users not interested in segwit
transactions may prefer to keep the cost of their node lower.
