Initially I thought this was a useless/dumb idea.
On reflection, I like it - it's weird. Old internet weird. Like someone with a couple hundred bucks and some time on their hands wants to do something they think is fun or funny... it feels human. I think we need more of this. Extra points for using a sketchy o365 form that looks like a scam.
Felt the same way initially, but you are very much right that this feels like a throwback to a more playful time about twenty years ago. Put in a request for the OpenBSD src repository, which is too big to fit on a CD these days and I am looking forward to see if/how they square that circle. OpenBSD used to ship their code on CDs up until about ten years ago, so it is a bit of a fun throwback in that way as well.
