You mean "microphones"?
People shouldn't be expected to use alternate controllers. And of course, adding Vive controllers also means buying and setting up lighthouses, which defeats much of the point of the WMR headsets having self-contained tracking.
And in terms of cost, adding a pair of Vive controllers and two lighthouses adds over $500 to the setup, or around $600 if you want the new Index controllers, effectively doubling the cost of the headset. Spending $600 just to get a decent pair of controllers does not seem practical. Likewise it shouldn't be expected that people will already have such equipment on-hand. The majority of existing VR users have headsets that don't use lighthouses, and a lot of the people buying one of these will be first-time VR users, considering how small the existing VR user-base is.
And why shouldn't reviews complain about it? Complaints are likely to lead to the hardware getting improved in future devices, so they should be in your best interest.
