UPDATE: I found this issue explaining the relicensing of rust game engine Bevy to MIT + Apache 2.0 dual. Tldr: A lot of rust projects are MIT/Apache 2.0 so using those licenses is good for interoperability and upstreaming. MIT is known and trusted and had great success in projects like Godot.

RedoxOS, uutils, zoxide, eza, ripgrep, fd, iced, orbtk,…
It really stands out considering that in FOSS software the GPL or at least the LGPL for toolkits is the most popular license
Most of the programs I listed are replacements for stuff we have in the Linux ecosystem, which are all licensed under the (L)GPL:
uutils, zoxide, eza, ripgrep, fd -> GNU coreutils (GPL)
iced, orbtk -> GTK, QT (LGPL)
RedoxOS -> Linux kernel, most desktop environments like GNOME, KDE etc. all licensed GPL as much as possible
A conspiracy theory explanation is not necessary as it:
It doesn’t take a conspiracy theory explanation to observe how classic corporate anti-FSFers are very content with social licenses (CoCs) being elevated to a position where they are considered more relevant and have more signal power than the software licenses chosen, or how many new-gen open-source contributors have no problem singing the New Microsoft (and the likes) praises… etc
