The thought process is, I think, that those in Bronze League realize that experienced players with plenty of upped cards grind Bronze to score some easy rares, though they have should probably be playing Platinum by that point. I know many of you, myself included, are guilty of just heading to bronze since it's pretty easy to get through. If you have a great upped deck, and realize you can grind bronze more efficiently than silver, you're going to grind bronze. There are few actions "beneath us"; if it involves scoring a rare card with 6 quick bronze games rather than 5 uncertain silver games, you'll go against bronze. Thus, being creative with their decks would equate to virtually no wins for anyone stuck in Bronze League, and thus no electrum. Upped decks are simply too good for the meager buffs Bronze League can afford with their 19 skill points. Thus, many of those in Bronze League collectively realized that aether stalls, while boring, have a great chance of stopping an upped deck not prepared to handle it. And so, I end with the sad conclusion: Copious amounts of Mono-aether stall in Bronze isn't their fault. It's ours.
