You don't have to supply (i.e. buy) your own hardware, but you might have to pay for the power supply.

On the contrary, you likely have lower commuting costs.

However, the more important aspect might be that you end up needing more space at home and the employer needs less space in the office. Working from your kitchen table is probably not the best idea in terms of ergonomics.

In my opinion this aspect gets few attention in the discussion.

Many people (prior to Covid) did not have a desk and chair suitable for WFH (I did, but many of my coworkers didn't). Chairs and desks are hardware.

Many couples do not have two spare bedrooms (especially in the Bay Area) to work in. That means potentially renting/buying a larger living space, or converting living space into working space.

N=1, but my lower commuting costs are more than offset by the lack of company-provided lunches, snacks, and coffee.
