The rationale from the author of the package who adding advertising is enlightening and definitely worth reading.

This is highly unrelated, sorry, but does anyone know the zsh theme used in that post (https://feross.org/images/funding-screenshot.png)? I didn't see anything like it in the list of zsh themes (https://zshthem.es/all/). The colored arrows look very appealing if they're contextual, like if they denote the status of git files (deleted/edited/added).

My ZSH looks like that, though the arrows are less bold. I don't remember configuring it much, if at all. I think it might be close to the default theme.

In my case, the arrows are purely stylistic. They never change color or ordering.

Ah, I found it. It's the default(?) theme called "sorin" from zprezto: https://github.com/sorin-ionescu/prezto
