Eh... a lot of international cooperation is done in a single digit number of languages. That's why most international institutions, wether private or not, define 'official languages'. When it isn't, it often involves translators, in numbers ranging from a few to armies. Most software out there being freely supported by at most one person, do you really think any of them have the resources, time, to find multiple translators willing to work for free on translating their project? Or, heck, pay them on their own dime for it? No. So most developers know that if they do not work in a language that will be understood by most other developers, their work will essentially be useless to everyone, no matter how great it may be. Honestly, we're lucky to even have a lingua franca. It could be Egyptian hieroglyphs, for all I care. It just happens to be English. And that is fine by me.
