What’s a Why-Not Report?
It hearkens back to the days of old. When we could read about the downside of vendors, instead of regurgitating marketing. A whynot report is a negative intelligence report focused on negative historical vendor events, weaknesses, failure patterns, and competitive disadvantages, essentially answering “why not” this vendor as a curiosity of thought and conjecture.
EXECUTIVE SUMMARY
Google Cloud Platform demonstrates critical reliability and authentication weaknesses in 2024-2026 with multiple major outages, privilege escalation vulnerabilities, and OAuth flaws affecting millions. While GCP maintains strong AI/ML positioning, the platform suffers from systemic stability issues including a 7-hour global outage in June 2025, critical CVE vulnerabilities in Container-Optimized OS, Cloud Composer, and API endpoints, and severe customer service failures with a 1.4/5 Trustpilot rating. The company faces ongoing antitrust scrutiny and billing transparency complaints.
Whynot Score: 78/100 (High Avoidance Recommended for Critical Infrastructure)
Key negatives: Major global outages, privilege escalation CVEs, OAuth authentication flaws, 1.4/5 Trustpilot rating, billing account suspension issues, and competitive disadvantages in global reach vs. AWS/Azure.

- Severe customer service failures
- Competitive pressure from AWS/Azure
7. ALTERNATIVES AND RECOMMENDATIONS
7.1 Better Options
1. Amazon Web Services (AWS):
- Superior global infrastructure
- More mature marketplace
- Better billing transparency
- Stronger enterprise integrations
2. Microsoft Azure:
