I totally agree.
The site OP linked to at least warns about scammy sites and risks associated. It also tracks prices on official resellers.
I wouldn't use it to save a few bucks on an indie title, but it's a nice resource when waiting for a AAA game to become affordable.
If you self-host, Vaultwarden is both easier to maintain, and free.
I switched from Shield to ATV when one of the system upgrades half-broke Plex for months.
ATV is beautiful and foolproof, also much better at connecting to various Bluetooth accessories, but so limited software-wise (compared to sideloading non-TV optimized apps on Android TV).
Another question is whether these images are useful at all, regardless of client and network. These are just text posts…
Looks neat! I didn't see Docker install instructions or even a link to the image on a registry, yet there is a Dockerfile. Do you support Docker-based self hosting?
