At the same time, open licenses allow you to adapt and replace components as needed. In many commercial solutions, the contents are more closed, which can make it more difficult to gain full insight into architecture and dependencies.<\/p>\n<\/div>\n<blockquote>\n<p>\u201dWith open source, you gain real influence.
