The way to win is to use system LINUX, which is open source code. Can be used as a successful example. You can steal classes with software that doesn't open the source code to make an example. The main direction is the monopoly of some manufacturers' products caused by closed software. The attack point and argument is that it is best to attack where you are good at it. it doesn't matter

Two arguments:

First, to talk about the high efficiency of open source, anyone who knows something about sociology can talk about it.

Second: the other party must talk about not open source, which is conducive to copyright protection. We can say that non-open source is precisely the source of power for piracy. Open source will change the profit model of software manufacturers and solve the piracy problem. Because in the open source mode, vendors do not make profits by hiding code, but by providing services.

The second point is a bit short. Does that make sense? At present, I can only think of this point of the other side's argument, and I haven't thought of the rest yet. So the second point is still very lethal.
