These discussions (ie, everything that follows here) would be much easier if the crowd insisting on the OSI definition of open source would capitalize Open Source.

In English, proper nouns are capitalized.

"Open" and "source" are both very normal English words. English speakers have "the right" to use them according to their own perspective and with personal context. It's the difference between referring to a blue tooth, and Bluetooth, or to an apple store or an Apple store.
