To be honest, a lot of the big PvP factions that used to play here have quit Empyrion entirely because they're tired of the bugs and the lag, and Eleon has indicated they're still very PvE/single player focused on their current development, so it's unlikely that PvP concerns will be addressed anytime in the near future - which frustrated them to the point of dropping the game.
The majority of HF players who used to play decided they didn't like the game. It's pretty much just Pat left on the server, from the forums. I don't play much any more because I don't have the time to invest, with all the other projects I've got going on. But because there are still 10 or so people who still log in (in 2s and 3s at a time, granted), I still keep the server up because it doesn't cost me anything - it's all paid for hardware that I physically own (I can see it from where I'm sitting in my office at work) and wouldn't have anything else to do if I took the server down.
I wouldn't blame you if you went to another server. I might suggest Renntech, they have a mixture of PvE and PvP and a very active community.
