How do you get scam from this paragraph?

"With F1, we have built a novel hybrid system that combines the scalability, fault tolerance, transparent sharding, and cost benefits so far available only in “NoSQL” systems with the usability, familiarity, and transactional guarantees expected from an RDBMS."

If you don't like NoSQL solutions, or they don't fit your project's needs, don't use them. There's no "scam" here.
