Maybe after 3 decades it is time to stop viewing "GNU/Linux or Linux" as a single entity/organisation. This is such a naive view.
This rant all over again is like complaining that the IT industry is fragmented and we have Google, AWS and Microsoft fragmenting the cloud offering, or that Render and Fly.io should not exist because Heroku was already there and people should just work for Heroku and make it a better product. Or that Apple and Microsoft should be working together. Or that Microsoft, Sony and Nintendo should stop duplicating their efforts and only offer a single, well made game console. Why have we so many cars brands? Why can I buy so many different yogurts?
