While I'm no fan of these companies, I'm not convinced by that particular argument for FOSS either. Imagine the world where we would be always iterating on one

While I'm no fan of these companies, I'm not convinced by that particular argument for FOSS either. Imagine the world where we would be always iterating on one lineage/model of refrigerator, each automobile type etc. instead of many companies rebuilding basic stuff. I don't believe we would be better off. Not all progress can be driven by consensus and iteration, some needs to be done by competition, divergence and outright discontinuing old approaches.
