[116] Its members denounced "a festival with disastrous ecological costs, financially disproportionate, reserved for a public with (very) high purchasing power, adding noise and visual disturbance to an already overcrowded mountain".

[120] On 29 July 2017, the Unite event in Parc de Can Zam, Barcelona, Spain, was cut short after the stage caught fire due to a "technical malfunction" causing over 22,000 people to be evacuated.
