If he has actually seen theft, he's obligated to report it to his manager and security. There's absolutely nothing wrong with people using their native languages as long as they switch to the office language if you ask and whenever you're participating—you should see how many languages are in daily use in Amazon offices all over the world. This asshole is just spewing racist and xenophobic stereotypes about Indians. Smelling like Curry mentioned right before implying engineers making 150k+ TC are stealing shitty $15 keyboards. That's not a fucking observation, that's racist propaganda.
Products don't handle their own billing, what the hell are you on about? Products just generate metering records. All bill computation and aggregation and all the rules and pricing models and discounts and tax calculations are done centrally in dianegon's org.
AWS Billing is not exactly prestigious, though. It's a sad space buried under the weight of literally decades of underinvestment and unsustainable legacy, layer upon layer. Many parts of AWS are exactly like this, and to be fair the leadership in Billing is really good, but the history of underinvestment makes work in Billing anything but prestigious. You're the cleanup crew for the shit that piled up on a toilet clogged for decades.
AWS Billing might achieve some prestige if they ever manage to launch billing as a service, but that's years away.
Most products do send real time metering events to AWS Usage, which is the intake side of the centralized billing pipeline. Before a reorg about two months ago, they were both part of a single org, Metering & Bill Generation, under ajassy/cbell/kkufeld/dianegon. That's why they process over a quadrillion metering records per month. There are a few service teams that have not onboarded, but they are the exception, not the norm.
