I'd be up to contribute some funds to have a $5 DO droplet serving the website for some time as well. I'll start by committing to one year of hosting ($60). I'll never buy a Nissan because of their actions against nissan.com, but somehow it doesn't always feel like enough.
Probably not even necessary to do that much. Point it at Cloudflare backed by an S3 bucket with a single "in memorandum" page and host it until the end of technology as we know it for ~$1.
I've learnt my lesson to depend as little as possible on vendors with specific technologies when you want to keep something alive for a long, long time. The less reliance on specific closed-source & cloud technologies, the better.
