Re: [Trisquel-users] Why does no insider disclose the non libre computer software?

In medieval cities, craftsmen tended to form associations based on their  
trades, confraternities of textile workers, masons, carpenters, carvers,  
glass workers, each of whom controlled secrets of traditionally imparted  
technology, the "arts" or "mysteries" of their crafts.

The guild was made up by experienced and confirmed experts in their field of  
handicraft. They were called master craftsmen. Before a new employee could  
rise to the level of mastery, he had to go through a schooling period during  
which he was first called an apprentice. After this period he could rise to  
the level of journeyman. Apprentices would typically not learn more than the  
most basic techniques until they were trusted by their peers to keep the  
guild's or company's secrets.
