Fascist governments, historically, have had a close relationship with corporations in their respective nations, to the point where they, in many ways, effectively become another arm of the government (in all of the bad ways and none of the good ways). If a corporation chooses not to align themselves with the regime, they risk being targeted.

Look for any remaining regulatory agencies to be used as cudgels against perceived foes. When the IRS starts going after [insert corporation here] because the CEO didn’t kiss the ring fast enough, etc.

There is also a whole lot of manufacturing consent going on, but that might only be somewhat related.
