That's not my call to make, I'd say its highly context dependent. Some politics may be very relevant to a line of business, others less so.
In any case I'd say the issue is often not about having the particular political opinion, it's about translating it into a type of activism that does damage, by creating internal division, distractions, generating bad PR, etc. These things can spin out of control, forcing business leaders to pick between multiple evils.
