Nope, it's not damaging public trust and harm miners. In fact, it's giving more people in the community to be trustworthy with this process because halving is actually a good strategy economically for Bitcoin to thrive more and gain more of its value.

As for the miners, they know what they're doing and have known this for so many years and if they're not in favor of this and been harmed by it, most of them have already stopped mining and the difficulty of mining should have dropdead long ago but it didn't.

No doubt, thanks to halving and mass adoption that creates more demand.
