It's not the length that's the issue, it's the content.
Complaining about donations tapering off when you fail to implement the exact features that people expect and want when they're donating to your project reeks of being completely out of touch with your fanbase. Of COURSE the people trying to pay you to make their machines work on Linux want all the features to work. OF COURSE they want working sound, all of their potential battery life and support for external displays... wtf did you expect?
I understand that these are herculean feats that were never explicitly promised, but the communication could have been clearer. Hell, a few sentences later this person is arguing that their distro can "totally be daily driven" and is being done so by thousands of people... NO, it's a broken alpha that lacks support for basic hardware features. Be clear about managing user expectations and you will have a much better time... but then there would have been less hype and less donations initially, so that's also not an option. Hence the social media crap mentioned in the /. summary.
Lucky for me, I hate Mac keyboards so my Linux-on-ARM ultraportable laptop hopes are pinned on Debian for Snapdragon Elite... maybe by 2030? Until then, as long as I can keep upgrading from one Thinkpad T14 to the next I think I'll be fine without Asahi.
