Oh man that sucks! I wonder if we could pull Alpine into our colo, we recently upgraded to a full rack from 2U (it was cheaper than a quarter rack!) and have a ton of space. Plus all of our libvirt/KVM HVMs run Alpine.
Now go ask your employer to donate.
I can think of maybe three exceptions my entire career, and none of them were especially huge contributions.
Slackware's the same way, most donations come from individuals and very small companies.
