Software libre alternativo a software propietario

Frecuentemente, me encuentro con personas que utilizan software ilegalmente, no por afán de enriquecimiento, sino porque no conocen alternativas de software libre que les servirían perfectamente: ¿por qué vamos a cometer ilegalidades e injusticias cuando tenemos disponible software libre perfectamente válido para la mayoría de operaciones que necesitamos?

La lista no es mía, pero tomando como fuente la página de "The Linux Alternative Project", transcribo aquí un  listado exhaustivo de software libre que puede ser utilizado a discreción y para que sirva para rebajar la ilegalidad en el consumo de software.

Muchas de estas aplicaciones libres tienen una versión no solo para GNU/Linux sino para Windows, por lo que el sistema operativo base que se utilice no debe ser una barrera infranqueable.

Que lo disfrutes.

También son muy útiles los servicios que nos presentan alternativas mediante búsqueda. Aunque en ingles. 'Alternativeto': http://alternativeto.net/ es quizás de los mejores, porque nos da una descripción de cada alternativa y su popularidad entre los usuarios, que pueden votar o proponer nuevos programas, aparte de otras funcionalidades que ofrece esa web.. Otros servicios de este tipo son: Osalt: http://www.osalt.com/ (en inglés), Alternativa libre: http://freealts.com (en español) Linux App Finder: http://linuxappfinder.com/alternatives (más enfocada a usuarios Linux) aunque hay más y seguro que alguien puede aportar más referencias.
