Yes Hesham, we have a really nice week by debating the topics and playing role about open sources movement. In our debates, nobody said opens sources was not good or useful. The debates were about what open sources movement is, how we can use them, what the points to be considered are.
It is obvious that open sources are so useful and helpful in terms of free accessibility, more resources, collaborative and constructive learning, saving time. On other hand, we need to consider legal rights (copyright) to use them. Also, in open sources movement systems, it is difficult to control and implement the accuracy of information and source.
