I believe the goal of this disinformation is to cause democracy to undermine itself. I think that whoever is spreading this thinks that once we're all accustomed to YouTube and Twitter banning mostly harmless urban legends, then soon they'll fall down the slippery slope toward more advanced silencing of politically unpopular opinions or whatever. I don't think it'll work, but it's the only sensible explanation I can think of. I mean if a state actor is pouring hundreds of thousands of dollars into promoting this disinformation, there must be some anticipated ROI. And other possibilities like "make people in the west distrust 5G so Huawei can stay ahead" and "promote general distrust of people in power" don't seem as plausible to me.
