So Bioware's plan is to:
1. Provide an example of something (Dedicate an entire mission/charachter/race to it).
2. Provide another example of something confirming what was previously established.
3. Say that it actually isn`t true, and you're supposed to know that?
This works with both AI being actually being benevolent instead of automatically evil (Geth, EDI) and the Mass Relays.
Also, IDT is not an ending, it is the openign to a NEW ending where there could be far more choices than
I am the squid of the vapor surrounding your dreams, sorrow, nightmares, and bootie pants. So watch out about that.
