There is that weird conspiracy theory that soybeans contain an estrogen adjacent substance which makes men more feminine. Complete nonsense but it gets especially funny when these people are advocating for cows milk instead of soy milk, because the former actually contains mammalian estrogen.

Honestly, I would go with a managed Nextcloud solution like Hetzner Storage Share or another reputable provider. No hassle of updating and securing the server, no data stored at Google or Microsoft, and easy to administrate by people who aren’t expert system administrators in case you are no longer available. I also went with that route for my personal instance because it was actually cheaper than hosting it myself on a VPS.

There no need to choose on over the other. I host all my podman containers in a Proxmox VM.

I know the type. Usually the kind of confident know-it-all who refuses to learn anything but delivers changes really quickly so management loves them. I had the misfortune to fix such a project after that ‘rock-star’ programmer left the company. Unfortunately the lack of professional standards in our industry allows people like that to continuously fail upwards. When I left the project they rehired them and let them design the v2 of the project we just fixed.
