Actually the CEO of SBST is wrong, there is still room for more bus
services if LTA don't interfer so much, like limiting express bus
services because of a lame excuse of duplicating MRT, drawing
territory lines for 2 bus companies and limiting other bus company
with more resources to provide better bus links and networks,
refusal or slow advancements to upgrade and improve bus
infrastructures to make buses a faster yet more affordable choice
for commuters over rail, etc.
from a macro perspective, govt's move makes sense.
"competition" might actually lead to worse results. especially
if the competition is not perfect, it never will be in Singapore's
case. the market is too small. but competing within the same modes
of transport will lead to conflicts in (our) interest. the best
solution is SMRT 100% rail, and SBST 100% bus. it is more efficient
and there's still competition (think 95/96 fleet upgrade in lieu
with KR Station opening).
there isn't a "best" solution actually. just trade-offs.
