The issue was that it made it very easy to grief people who were trying to level up by questing, as high-level people could become ghouls, and then just wipe out the quest givers (in the very first form they could also wipe out the flight masters pretty easily, but I believe that got dealt with in the second iteration), and generally NPCs like repairs and selling NPCs, and people were systematically keeping quest givers dead in places like Redridge, Westfall, Barrens and so on - all the lower-level zones. Back then, that basically stopped people from leveling up, because quests were essentially the only way to level up. It was large-scale continuous griefing. It didn't happen in the higher-level zones because there were high-level players around to fix it, and sometimes high-level players would come and fix it in low-level zones, but that didn't last, because they'd fix it, then leave, but the griefers would just hide out until they left. I personally had to keep logging over to a max-level character and swapping to them when the griefing started, then going on to the character I was trying to level for fifteen minutes until it started up again.
It's not true that it was to "simulate the corrupted blood plague" AFAIK. I've never heard that claim before it and seems like an asspull, but perhaps you can source it? Nor a "real" (?!?!!?) zombie invasion. The goal was to have a really cool event that made the game feel different and exciting for a while. If you were only playing at max level, that was maybe partly true, especially initially, but it rapidly devolved into just trying to grief people. At low levels, at least on both the servers I played on (higher pop ones), it was a literally 24/7 grief-fest, where people weren't really after your character all, just trying to keep the NPCs dead to prevent you do anything, which didn't feel at all like a "zombie invasion", but just like, organised griefing. Indeed, it was similar to when high-levels from the other side came in and did the same thing, except it worked way better, and it was usually your own side doing it, so much easier, because you couldn't corpse-camp them, as soon as they weren't zombies you could no longer attack them.
So I think all that is why they've toned it down so much.
On the other hand, the game is totally different now and that stuff is much less of a risk, and full scaling (rather than just the weird scaling the zombies had back then) and places in other timelines and stuff (where the zombies should be banned from going, because it's another timeline) mean it's way less of an issue, so I think they may have gone too far.
