Like what the title says. There’s always a catch unless it’s FOSS. So, what is the catch with them giving games for free that you can keep forever? What will the developers of the games get as a thank you?
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.
much thanks to @gary_host_laptop for the logo design :)
You could download and play the games on a machine that is never used for any other purpose, but it would still be able to collect biometric data (mouse movement, keystroke patterns, voice if you have a microphone, etc.) and probe/fingerprint your network.
Short of a dedicated machine, the closest you’re likely to get is a hypervisor-based virtual machine. Of course, that won’t safeguard your biometrics or (in most cases) your network, either.
Such a machine would be safer if you never gave it network access, so it couldn’t exfiltrate any data that it had collected, but downloading games requires network access at some point, and it would only take milliseconds for a “helper” process (perhaps quietly installed/launched with the game) to leak the data.
In general, hostile code will always be unsafe. If it concerns you, it’s best to avoid it entirely.
