(Bandwidth is ambiguous in this context so I'll use "data transfers" instead)
I personally don't see the outrage. AmaGoogSoft overcharges for data transfers because they know they can get away with it and that lowering it won't attract more customers.
Customers with transfer-heavy applications will always buy their servers from providers with unlimited transfers like OVH[0][1], where you can do hundreds of terabytes a month with no extra charges (1.5 Gbps * 3600 * 24 * 30 = 486 TB). Even if AmaGoogSoft lowered their transfer prices by 100 fold their pricing still can't compete with OVH.
Companies with enough engineering resources can always go with the best of both worlds: transfer-heavy servers on OVH, and "regular" servers on AmaGoogSoft. The expensive data transfers will only hit smaller outfits, but these customers won't switch because it's not worth the hassle to split your hosting across two providers.
