I think it’s more so that the kind of people contributing to these projects are on balance not that interested in doing the marketing work.

Can someone explain where the Y comes from? Is this something like, there exists a mother relation between this X and some Y?

The reason for this is that git rebase is kind of like executing a separate merge for every commit that is being reapplied. A proper merge on the other hand looks at the tips of the two branches and thus considers all the commits/changes “at once.”

You can improve the situation with git rerere

The numbers are different because the site doesn’t naively count every line but merges some as a single package. For example, at the very top of the Debian list we have 0ad, 0ad-data, 0ad-data-common. These are all counted as one single “package.”

One might argue that doing the comparison in that way is more useful to an average user asking “which distribution has more software available.”

They say that because https://repology.org/repositories/statistics/total says so. Debian unstable has 38k packages according to that page.

Mac users, and actually most laptop users, don’t give a shit about the things you mention. They buy it, use it for some 2-5 years, then sell it and get a new model. Upgrading hardware is way too complicated for most people. They don’t know or care what a BIOS is. It comes with the OS installed and that’s the only thing they would ever want. Turn it on, use Safari, outlook, and office 365, maybe some tool like Photoshop/Ableton/etc, that’s it.

I mean iPhones are the same right? They lock down everything so it’s idiot proof and they control the environment exactly so they can maximise the smoothness of the experience.
