First, I don't believe that "cancel culture" exists. There is no systemic problem of people being fired because their ideas are too radical. People generally get fired because they say something bigoted or do something that's fire-able anyway. This is a separate problem:

There is a problem of institutions that treating Internet commenters as if the customer is always right, and everyone is a customer. I think it partly has to do with viewing news as more of a consumer product than something that has a public service element.

And employers need to know how to differentiate between bad faith critiques and legitimate concerns, & use (godforbid) critical thinking skills to separate the two. They need to consider the complaints on their own merits, & in the context of the employee's work and known intent

Just to use an example; someone my TL compared Will Wilkinson's firing to James Damore's, as if either of those cases were about radical ideas. I find what Damore was advancing despicable, but from a corporate perspective, he was also a walking gender discrimination lawsuit.

There were multiple reasons to fire Damore, and at least one that was rooted in sheer practicality. Wilkinson and Wolfe's firings were both predicated upon taking the critiques of bad faith Internet commenters at face value, as if they were meaningful and sincere.
