The only advantage is cheapness, for personal use.

If you’re a government agency or a company you don’t care about saving $14/month, you want a secure provider. And these hosts are not secure, you’re basically just on your own.

Without hiring/being a cloud expert, it's hard to be sure that you didn't leave some door wide open due to a configuration error. Both approaches offer more than enough opportunities to royally screw up.

If you're a government agency or anyone for whom a security failure costs more than sending an apology letter, you should really have your equipment in a locked rack, if not on prem.

Speaking for myself, managing a team of 3, the simpler management interface on Hetzner compared to AWS is a major professional advantage.
