> Yet, according to Stallman’s definition [of opensource], software needs to be free: [Free as a bird, Free as a beer]
This is totally wrong. Stallman focus on freedom to use the software, he never stated that the software need to be free of charge. Yet, Stallman hates the word opensource because is it to vague and it does not guarantee the freedom to the user. Stallman use the term free software and or libre software, and mean free as in free speech only not free beer. While Free software and opensource software's definition may overlap a bit, it is not the same, for example, some opensource license does not allow making a modified version and using it privately. Free software focus mainly on users' essential freedoms, while the opensource initiative focus on practical benefits only.
