Two things need to happen to change academic publishing:
1. Being a peer reviewer for a corrupt journal needs to be viewed not as a feather in an academics cap, but as a contribution to a corrupt system. Basically reviewing Elsevier journals should hurt your carrier not help it.
2. A new system of publishing needs to arise based on well-compensated (and hopefully more effective) peer review and cheap access.
Start-ups can address #2, but you will be dependent on high profile academics like Gower constantly speaking out against the old system.
