I can't read this article because of the paywall. Are they saying that taxable tips are subject to payroll taxes (which employers pay out of pocket)? That would actually benefit both employers and employees in some sense.

Some tipped workers, like bartenders, can make more in tips than a junior software engineer lol. Less taxes definitely helps their cause.

If you are concerned with indirect effects, there's quite a few pros and cons that you could extrapolate from the no tax on tips policy. These arguments are far less compelling in general.
