Cloud's losses ($1.8B in H1) are about 4% of the operating income of the money-making parts ($46B in the same timeframe). Sure, a billion here and a billion there, pretty soon you're talking real money. But it's hardly "sucking the company dry of its profits".
So you're suggesting that the accounting is fradululent, and nobody figured it out except you? Not the auditors with actual access to the raw data. Not the hedge funds who could have made a pretty penny by shorting the stock and then releasing this information. Not even any whistleblowers who would presumably be eligible for an award.
