Ah, thanks for noticing my domain name :D
However I have literally never played gregtech before, I purchased this domain name without checking whether "gregtech" it's used by any other projects.
Not all subscription based services are malicious. Case in point: Bitwarden is incredibly cheap (10€ per year) and is the best password manager I have ever used. Also services that need constant upkeep costs, such as your carrier, ISP, perhaps even a VPS (I use Hetzner for that), have simply no way to be one-time payments.
How is monero useless?
