> pace of development is doomed to be too slow

When the new leadership team took over, they announced that they would prioritize upstreaming the existing work over adding support for newer hardware.

Upstreaming their changes into the kernel took time.

Now the announced that they had started work on the M3 in February and things are progressing well.

> On top of the above, we also have PCIe, WiFi, Bluetooth, NVMe, keyboard, trackpad, and other core SoC block drivers working in Linux for M3 series machines. Most of this work has come by way of Yureka, who has been very busy hacking on both m1n1 and Linux with her M3 series machines for a while now. We still have a ways to go before we can start enabling Asahi Installer support for these machines, but progress is rapid so watch this space!

That sounds more like talented people doing meticulous work than doom.
