Oddbean new post about login | logout This kinda feels like a strawman. If it's the easiest option out there, why not use it? If the necessity arose to switch, I'm sure many nodes would migrate.
It really is that easy. The problem is that for the vast majority of users and even a large majority of systems professionals, self hosting production grade anything is a daunting task. That simple node offers no backups, no failover, likely only a single hard drive which increases risk of failures. TBH most are competent enough but not confident enough to take this on.
