Google employs 200,000 people. Suicide rate in the US is ~13 per 100,000 per year. This means there is an expected base rate of Google employees committing suicide per year regardless of working conditions that is likely higher than just 2. Maybe there is a real issue but two suicides within such large number of employees isn’t statistically significant.
EDIT: I added "statistically" in the last sentence to clarify my intended meaning.
