The article seems to be focused on the potential risk of interfering with medical devices using the same frequencies for communication. The more obvious danger of a microwave oven is that you must not stick your hand inside a microwave with a defective door sensor while it is running as it will cause heating in the same way that it can boil a cup of water. I will note, however, that the statement "microwaves are non-ionizing" does not automatically imply the common follow-up that "the absorption of microwaves cannot have any chemical effect other than indirectly through heating". This is evident, for example, in that proteins in the human eye undergo a chemical change in response to absorbing non-ionizing red light. Whether there is such a thing as a non-thermally microwave-driven chemical reaction is an open question in chemistry [1]. I feel the need to clarify as an addendum that nothing in this post suggests any danger associated with the use of low power microwave radiation from consumer wireless communication electronics.
