I had to read about him on his wiki page:
Many of Pink's remarks in interviews have incited controversy, particularly among
left-leaning indie music communities.
[12] Some of his provocations included "It’s not illegal to be racist", "This gay marriage stuff pisses me off", and his expressed "love" for necrophiliacs, pedophiles, and the
Westboro Baptist Church.
[12] His negative press reached a peak around the release of
Pom Pom, when detractors variously labelled him a "troll", a "
beta male", and a "misogynist".
[73] Fans argued that he is simply a glib speaker.

In December 2020, during a podcast appearance, Pink stated that he believed the recent election results were tampered by the Democratic party "in some sort of collaboration with China". He opined that Trump represented "an indictment on anything bullshit ... I'm so
gay for Trump, I would let him **** me in the butt."
[85] Furthermore, he voiced skepticism with the scientific community, saying that many of their claims, including those for
climate change, "probably [are] bullshit" and politically influenced, and added that he had disagreed with his father, a medical doctor, about the effectiveness of the
COVID-19 vaccine.

I can see they don't want to be associated with him.
