Pretty standard really. You don’t want contributions to the codebase come under questionable copyright concerns, or the original creator to revoke the code 4 years later causing huge headaches potentially.

You typically have to sign these types of CLA’s whenever you need to contribute to any serious project. I’ve had to do it for Google and Microsoft recently, and I’ve done it for various other open source projects as well.

Still that shouldn’t concern users/gamedevs as they don’t contribute to the engine code typically. Only if they want to upstream changes back into the engine publicly they would need to sign it ofcourse

Besides some countries in the EU already have electronic ID identifiers. They can just contact them to verify I’m claiming who I am without this weird “yeah we need a picture of you, and look through your webcam”. Banks don’t need to do this to verify who I am, so I don’t see why “X” needs this weird privacy invading process

Thankfully I don’t care about X (lol), and with more and more of my industry moving to mastodon I’m quite happy that I need it less and less to keep up with papers and articles
