Consensus is really needed, generally speaking, so that the phrase "open source" does not lose meaning and so that the ecosystem avoids fracturing from a gaggle of certifying bodies
I think challenging the consensus is equally needed (and high time in this regard, IMHO). To me, 'open source' lost its meaning a while ago, and I welcome new ideas in this space.
When did it lose its meaning? What did it mean that it no longer does?
