Here’s a dev explaining it: https://lemmy.ml/comment/2618947
Apparently they do chargebacks, which costs the gamedevs money.
This is something that should have been in the opening post.
It explains why using these sites actually causes harm.
Instead of getting a game at a reduced rate without harming the dev much (just losing a sale) you’re actually harming the dev.
This is something I didn’t know and now I’ll look more at discounted games on official platforms instead of these key sites.
I recently wrote a blog post about the new NAS I built myself and why I didn’t choose for a RPI 4. https://jeroenpelgrims.com/diy-nas/
I think it terms of price it won’t be much more expensive than an RPI NAS, but you’ll get more performance and stability.
If you don’t care about power usage and/or connecting stuff through USB you can also buy some older hardware instead.
