Charging for lectures that already exist on the internet has never made sense to us. Every track, module and challenge is free and will stay free. What is worth paying for is the machinery around getting hired — the questions really being asked, applications tailored and submitted only with your approval, and people inside the companies you are aiming at.
Watching a derivation is not learning it. Every module ends in something you have to beat, and the checker knows the answer.
The material is all online already. What is missing is a path with no gap where you were supposed to already know something — which is what the eight tracks are.
Plenty of people who could do the job never get one. That gap is what Pro is for, and it is the only thing here we charge for.
