Honestly, the real definitive fix for this, and many other issues that are all related, is a big economy overhaul and a rebalancing of commodity, ship, equipment etc prices. The crux of the issue is that money making is too easy and in the majority of cases, there's no reason to play certain factions over others, as one ID/IFF/Ship/Route combination will be king until it gets nerfed - or whenever the next trade event is.
People have been clamouring for such an overhaul for years, with many individuals stepping forward to undertake the necessary work to make something like that come to fruition. Unfortunately, they've never had the chance. The current awful state of the economy, the factions that have suffered from it, the sci-data debacle, sudden death of piracy and decreasing player activity are all direct results of an economy that has stagnated.
