Richard Stallman was right since the very beginning. Every warning, every prophecy realised. And, worst of all, he had the solution since the start. The problem is not Richard Stallman or the Free Software Foundation. The problem is us. The problem is that we didn’t listen.
There’s more to it than just having free software. The source code is important too because it lets people learn from it, improve it, and use it to write or improve their own projects. Free software is only half the equation.
Unless you mean pirate the source too, in which case yeah absolutely but easier said than done.
All right, that’s an argument. Also, having fun from coding is also a valid argument. Though, from my experience, it is easier to start learning programming from some simple, isolated cases, as in thextbooks, than from real life programs, which can be very nasty and domain-dependent.
