What’s the difference for a real user between using X11 or Wayland nowdays? I haven’t found anything useful on the internet, so I’m asking you. Internet articles on the topic (and about WMs too) seem to be advertising slop since they explain anything but the real things. Also, if anyone used the XLibre fork, I would love to hear about your experience with it.
Two things, one as previously mentioned the codebase is a mess and even the best developers working on x11 tend to introduce regressions (the xlibre dev isn’t so this is amplified). Second it absolutely is a conspiracy because red hat did everything in the power to save x11 until eventually they just kept using it (tbh it needed to be replaced two decades ago). As for your last point linux won’t have a future if its aggressively held back by an army of enthusiasts who demand things never change and fragmented until software support is non-existent.
