All these people were there to offer praise.
If you set aside the physics academic circle, scholars from other fields unanimously opposed the construction of the Large Hadron Collider. They simply lacked a say in the matter because they weren't researchers in physics.
The reason for opposition was simple: the Large Hadron Collider project required a massive investment, and domestic research funding was limited. Since the collider project would consume a majority of the funds, other areas of R&D would inevitably face budget squeezes.
This was inevitable.
Even if additional funds were allocated to the collider project, they wouldn't cover the total cost. If half of the additional funds could be invested, that would be considered good. With the collider project taking up "tens of billions," other research fields would have to "tighten their belts."
