rauschma, Downsides of open source software (OSS):
– Many factions—e.g. many Linux distributions & desktops. Because OSS attracts people that want to write their own software so that it exactly matches their needs(?)
– UIs seem often less polished. Because OSS has more programmers than UI designers(?)
Other than that: It’s ironic how much open source helps companies—especially small ones. IIRC, the first internet boom would not have been possible without open source projects such as Apache.
