The current endings don't make sense. It just doesn't work, plain and simple. Unless their intention was to completely destroy the universe they spent three games and metric butt-tons of other media creating... In which case I'm just sad they wanted to do that, and will move on. I realise this single person doesn't speak for Bioware, but this is hardly a matter any of them should be joking about.
If they intend to keep this universe rolling, and intend to create more Mass Effect games: This has to be undone or at least elaborated upon. The current endings open up tons of questions and are riddled with plotholes - something no writer or game dev worth his salt would accept in his/her own creation.
Bioware reacted to errors in a ME book by saying they would get them fixed, because it was so blatantly obvious that the stuff in the book didn't work with the lore of the ME universe. Fans called those errors out and they said they'd get them worked out.
I quote what was said about the book:
The teams at Del Rey and BioWare would like to extend our sincerest apologies to the Mass Effect fans for any errors and oversights made in the recent novel Mass Effect: Deception. We are currently working on a number of changes that will appear in future editions of the novel.
We would like to thank all Mass Effect fans for their passion and dedication to this ever-growing world, and assure them that we are listening and taking this matter very seriously.
These endings don't work with the lore of the ME universe - unless the writers' plan was to destroy the entire universe. Why is it acceptable? Fans are calling Bioware out on the errors in these endings. Why? As the quote says - Passion and dedication to the ever-growing world of Mass Effect.
