Valid points, but they raise the initial hurdle. I run a dead simple and cheap (<200EUR) NAS at home for 5 years, just connected to the internet with DynDNS and masqueraded tcp ports http and ssh from my local internet uplink. I made regular backups to a USB hard drive. It was cheap, fast at home and usable from remote. Using only 20W, it was also reasonable cheap, roughly 40 EUR/year of energy costs, so over 5 years the system costed 6 EUR/month. For this I did not only get lot's of storage but also a reasonable computer to host arbitrary services on.

Today, you would probably classify this as indiweb or decentralized. I would just call it DiyO and always prefer it against some subscription.
