A common criticism of CSR from those on the "left" of modern politics $($also called liberals or progressives$)$ is that:

CSR is an unnecessary burden on the economy, and that society is actually benefitted the most when companies focus only on making profits.

unless CSR efforts are voted on and approved by the shareholders, they represent an unfair and unethical tax on the shareholders who are the ultimate owners of the corporation.

CSR efforts by corporations rob individuals of the ability to do good themselves. Since a corporation is not a natural being with emotions from doing good, corporate CSR is unfair to individuals who can feel emotions because it deprives them of the opportunity to feel good about themselves.

because the profit seeking motive is so strong, corporations frequently use voluntary CSR efforts to only appear to be behaving ethically when they are not, and instead tougher laws and regulations are more important to societal welfare than voluntary CSR$.$
