Generally accepted by who? You can find some people who are concerned about this stuff. 5G truthers and all that. But nobody in the evidence-based medicine community.
Nothing is entirely free from risks. That's part of why we do studies on things like this. But, for example, the second study on the page you linked concludes: "At the present state of knowledge there is no positive evidence that pulsed or continuous microwave exposure in the non-thermal range confers elevated risk to the health of the brain."
The mere presence of studies on a subject does not indicate positive evidence of material risk to health.
