It has not been taken away, as PWizard explained in the linked thread below you can download as many offline keys as you want for standalone trainers. Aurora however is a new product which works differently and we've had a discussion with the community on how to handle offline mode as either we limit it or we don't offer an offline mode at all. As we know how important it is for many users we decided to go with limitations.

I appreciate what you’re trying to say and it's moving the goal posts. The site could have been revamped, got integrated features and etc but have the same pay wall for an offline key. The program is just a revamped site, it needed code, digital assets and etc but it still does the same thing we paid for with the lifetime, except now there's now a paywall for an arbitrary reason. Again providing the same features we all ready paid for.
Where does the nickel and dimming end? Show me on page with no caveats, plain and simple English with no double talk. I've had this happen several times now with "lifetime" and it's disgusting. Don't believe it happened here, look at the Lifetime Plus. People said a new subscription for features would come down the line when lifetime was taken away and at first it was just cosmetic or suggestions.
But now it's a useful feature with a flimsy excuse to exclude it from people who are no longer paying to extort, no better word for it (coerce, manipulate, back against the wall), more money from them. I get you need to make money to stay solvent but you made an agreement and now your skirting the responsibility of that promise through a technicality. This makes you unworthy of further support due to you breaking the spirit of that agreement just so you can hide behind the letter of it.
I should point out to anyone else reading this, this will not stop. Sure they got a lot from kickstarter and maybe a few more subs but when that money goes dry in 2 to 4 years, the next feature to be pay walled will come. That might be Lifetime Plus Premium! For what exactly the editor? Next maybe Lifetime Plus Premium Mobile! To control it from your mobile phone. Next maybe Lifetime Plus Premium Mobile VR! Cause VR games are niche so to cater to that market they need more funding.
