What do you mean by this? Companies choosing the best option rather than the cheapest option is perfectly compatible with a free market. MS Office has been designed for decades to be easy to manage and support and has plenty of training resources available. LibreOffice still has plenty of rough edges in those areas. As an individual user, maybe those are worth overlooking for you. At the scale of a company where time is money, it's much more important to get something reliable.
Also, an unregulated free market always turns into a monopoly (or at best an oligopoly) eventually. It's been shown time and time again.
