It's frustrating that engineers, who should know better, design systems in such a way as to have single points of failure. We have the technology and knowledge to have reliable systems, but here we are.

Fashion and religion are well-known overrides for reason. And people who call themselves engineers are not immune.

Alternatives are being built. Consider migrating to Nostr repos and host a relay if you can: https://ngit.dev/ https://gitworkshop.dev/danconwaydev.com/ngit

The real underlying problem is hardware manufacturing (explained further here: https://news.ycombinator.com/item?id=49690354), which exerts centralizing pressure all the way up the stack. We should have pursued computer manufacturing in a print shops and printers kind of way instead of building large fabs, but that would have required foresight decades prior.

Is it a single point of failure though? Or just a convenient end point?
