That's like saying a tech company shouldn't report their revenue and costs for the first 10 years or whatever because it might not give people the full picture on what they might be worth.

Hillgrove had a legal obligation to report revenue and costs through their Quarterly 5B, which they met. They're not obliged to provide you with some commentary.

hiding the facts though makes people suspicious
