Current quantum computers are way to small and noisy for any practical applications. To give an example, the largest number ever factored using Shor's algorithm on a quantum computer (without cheating) is 15. These cloud services might be useful for researchers to test possible algorithms on. On the other hand, FOMO probably also plays a significant role in the emergence of all these quantum cloud services.
