There are probably other parts as well. Dissatisfaction against Apple for App Store has been high, may be for some Liquid Glass was the last straw. Omarchy had the highest number of Apple user switch to Linux. 100,000 downloads may be small numbers by Apple standards but even if half of that were developers coming from Apple Mac I think it is a pretty big shift.

The worst part, intentionally or not they left macOS 26 as the last release for all the Intel user.
