I don't recall anyone making any such demands. There was a thread requesting a toggle, though. Polite request =/= demand.
That was that thread - this is this one; this one is about toning the content down to 12+ rating.
I think you have that backwards. People who have requested the toggle - or would like less of certain kinds of content - are the ones constantly being told to buy something else. IOW, go away, we don't want your kind here. Classic bullying tactic.
You were the one who turned it around, or "backwards":
Bioware could save quite a bit of work and expense if they didn't build those things into their games. People who want them could take your advice and buy other games that fit their preferences.
Your statement basically reads that BioWare could take the sex/gore out of their games and then previous fans could buy something else. You don't see the difference? In the first instance people who are happy with the games are saying if you don't like it, buy something else. In the second the "demand" is there that BioWare change their content style and anyone who doesn't like the new lighter version can buy something else.
Appealing to a broader audience is a problem? Wow. Just wow.
By that token, as it has no sex or violence
In the Night Garden should be the greatest mass appeal TV program ever made. Toning down the content may well alienate existing fans - it may actually diminish the appeal. As I said, I've no interest in Mass Effect the peaceful negotiation simulator.
I'm not quite sure how you could go darker than turning every sentient being in the galaxy into slushees...
Not the subject but how it's treated... Banshees were getting there as was the Citadel body pile in the end of ME3.
However, overall the games empower the player and give you a sense of hope throughout the series before pulling the rug out from under you at the end. If they'd made the Reaper forces feel truly unbeatable from the offset, if there was no way to save everyone from the suicide mission, if you could screw up on Virmire and get
both Kaiden and Ashley killed - the game could be, and arguably should be, a lot bleaker in the overall tone.
Cerberus would have actually been a lot darker if they
weren't Husks under that armour in ME3... if they were just the dregs of humanity, the bigots, the racists, the murders and rapists all gathered under the banner of Humanity #1 - if they were committing atrocities not because they were Reaperised space zombies but simply because they're realised they can get away with it under the auspice of "fighting the Reapers"...
Or have deeper consequences than deciding the fate of entire species - individually and collectively.
Big consequences but all superficial. What difference does it make if you save Ash or Kaiden? The Quarians or Geth? Cure the genophage or not?
These are all massive but basically equate to icons in your list of war assets. There's no depth to the consequences.
