So to say that EIGRP is a hybrid would be correct. If you have any doubts, complaints, whatnot, contact the author.
This is a very week argument: quote from elementary CCNA (Cisco Certified Network Associate) study guide. I fully agree with noel's note in the beginning. Your quote: "And EIGRP has link-state scharacteristics as well - it synchronizes routing tables between neighbors at startup, and then sends specific updates only when the topology changes occur." The last part I would call asynchronous or event driven, nothing to do with maintaining full link-state topology table.
The point of the Bellman-Ford class routing algorithm is that router does not need to know full topology but only local knowledge of its neighbors. Historically this was significant when routers memory and CPU was limited and savings, real or perceived where important. The link-state vs. distance vector wars are over but the misconceptions remain. Calling it a hybrid sounds like a compromise remaining from these wars.
