It isn't even that the deduction went away, it must now be amortized over five years (an accounting trick on the part of Congress to pretend they're not spending money they are).
This hurts businesses more the smaller they are, but paradoxically it also hurts businesses more the higher percentage of their revenue they spend in payroll. Literally if you give your employees a bigger reward for their work, you're hurt harder by this ridiculous law.
