The poster isn’t saying they are simple. The poster is claiming they are complex enough that they are non trivial to create and maintain, and not expensive enough that it’s worth it for these companies to go through the effort to create an alternative. (50k per seat, which almost certainly is lower on an enterprise license, is about 20-25% of the cost of an employee, and probably lower when you consider the non salary costs of an employee such as benefits, payroll taxes, office seat rent, food, etc). The equation obviously changes when the lack of availability of the tool is an existential threat and therefore worth billions.
