Express your views on open source and based on your own experiences and Cognition

I would like to express my views on open-source and using my own experiences and insights-Linux general technology-Linux technology and application information. The following is a detailed description. In fact, most disputes over a certain issue in the Forum are caused by different contexts. Let a development system kernel discuss the importance of assembly with a development MIS, the situation can be imagined.

Advantages of Open Source:
1. Convenient for collaborative development in a wide range
2. Quickly understand the internal operating mechanism of the system for further development
3. Save money (linux is the hardware vendor's favorite-Maybe google is enjoying it-how much does it save?
4. Easy for beginners to learn
5. Efficient System Operation-open-source systems are never idle! (I'm sorry to take it out !)

Disadvantages:
1. Insufficient concern for user experience
2. Innovation is not enough, basically imitating
3. The upstream and downstream "ecosystem" is not formed-this is fatal! (You can be a Leifeng, but you cannot ask others to be as noble !)
4. Insufficient overall product management, resulting in too many versions and chaos (everyone wants to use them for their own purposes, which is determined by human nature)
5. High development and maintenance costs, non-black box-double-edged sword

Write it to this first.
