What’s wrong with GitLab?

This is a brand new project so I’m sure no apps are using this yet or even have plans to.

Yep, vectors. See https://github.com/onthegomap/planetiler

You mean how much faster downloading vector tiles are in comparison to raster tiles?

I think pre-rendering makes the biggest difference, rather than the type of tiles.

The author is talking about the server use-case here but it’s not any better for desktops either. I think it boils down to the fact that neither of these operating systems are designed for a single-user world like Android (or any other modern mobile OS) and so these security solutions are shoehorned into a world where they don’t really fit into. Because those (server or desktop) programmes have different set of expectations about what’s available to them, than say, an Android app that knows that it has to ask for permission first.
