PR comes from PR companies. A great book on this topic is "Toxic Sludge Is Good For You," which I highly recommend. PR is designed for mass consumption. If you poke around in the documentation on their websites which is designed for developers, you'll see that these computers cannot be used for general problem solving, which any computer (a Raspberry Pi, for example) can. If you go further and actually sign up for a trial account on these services (which I have done), you'll find that the "problems" they can solve are quite contrived and, as the OP points out, only consist of issues where the programmer already knows the solution. Quantum computers are not as useful as a Raspberry Pi. That's it in a nutshell.
