Perhaps the product this engineer works on does not pan out, maybe he unwittingly makes the company weaker by siphoning capital on a project that eventually fails. This seems to be a common case at Alphabet.

Indeed a company making flying cars and engaging in surveillance is clearly already not contributing 100% of their working capital to expand their surveillance capabilities.
