That would be a good start as TV 5 has the PBA already therefore they need a big network that will televised their games. However, if they still could not get into a big channel, I guess having it through live streaming platform like youtube is already good enough, for sure now many people are watching online too aside from their tv screen.
TV5 is also subsidiary of PLDT that Pangilinan owns and it is already good that they have a channel where we could watch but I mean there's no harm if MPBL itself will buy a frequency to host its own channel rather than just renting it. In today's time, people are already used to just watch it on an online livestream in their laptops/computers/cellphones but TV's are the traditional ones that we used to have.
