I don't think theyre being used as an example at all. A lot of these first generation platforms are still just trying to figure stuff out, and unless they all glob onto an existing platform, they'll never deviate from one another. Competition is good, especially to drive innovation in the early days of new fields of products like these. Most of the bigger companies have opened their platforms or pieces thereof, but that doesn't need to mean open-source. We should rely on legislature and right to repair to reign some of the anti-competitive bullshit they all pull in though, I do agree with that.
