I worked on EQ emus for 10 years so here's my take.
I don't blame Daybreak for shutting down emus that are profiting from their IP like this. Some of us emu guys are mad because they're not only profiting from Daybreak's assets but also our emu dev work. They broke the big rule. This brings heat down on all of us. The reason why there are not many more emu servers is BECAUSE we can't profit from them, and even if we could legally it's still a shitty thing to do. THJ's contributions to their own server/game amount to like 3% of the total code and asset base. Make up any number you like here but it's a single digit for sure.
I however do not like long copyrights. I would generally agree that EQ's earliest eras should be public domain by now, however THJ is using a much more modern client. The server wouldn't exist if the modern clients weren't available. Thanks to evil Disney copyrights last an eternity so that's the law.
My motivation for spending so much time on the emus is to preserve the game before it's lost forever. I consider myself a game preservationist/archeologist first and foremost. Most of my work is server agnostic and just researching how the game worked at a highly detailed level, and collecting mob stats. (I'm mostly retired from this) Daybreak is a company and thus only concerned about profit. EQ to me is a great cultural artifact that requires preservation. I want people 1000 years from now to be able to play it as it was like in 1999. When Daybreak changes the game over time, this is damaging the cultural artifact. It's like rewriting an old masterpiece of literature for a modern audience. I tried to save EQ from being erased. Modern EQ is not real EQ to me. If they kept a real classic server running then Project 1999 and TAKP wouldn't need to exist.
I did receive some donations for my emu work. The sum amounted to a very rough estimate of less than 10 cents an hour for my labor if you count every hour from 2013, which I would have done regardless. I never asked for a donation; people just offered unsolicited. I do think small unsolicited donations are fine and hopefully this doesn't make me a hypocrite. Anyway, hopefully Daybreak's lawyers don't go crazy with the litigation, because there are no winners in that scenario.
