Furniture for managed office space has different requirements.

If someone's unstable motorized desk tips over and injures someone at the office, it's a big problem for the company.

A cheap desk might have more electrical problems. Potential fire risk.

Facilities has to manage furniture. If furniture is a random collection of different cheap desks people bought over the years they can't plan space without measuring them all. If something breaks they have to learn how to repair each unique desk.

Buying the cheapest motorized desk risks more time lost to fixing or replacing it. Saving a couple hundred dollars but then having the engineer lose part of a day to moving to a new desk and running new cables every 6 months while having facilities deal with disposal and installation of a new desk is not a good trade.
