The kernel is the brains of the any Linux OS. It has access to every aspect of your system. Which is why they (EA) wants access. I would like to think you wouldn't put a device in your brain to have some 3rd party to monitor your entire body for bad actors.

Having this level of access to your system would allow them to see all the processes and files, scan them and create a fingerprint that's linked to your account. With the levels of violations that all governments are conducting in our lives it would be a small feat for EA to divulge this fingerprint for not only their own profits, directed ads and marketing, but anyone who would ask including government entities.

That is only one level. One other aspect is performance hits. Adding this kernel level monitoring will also take clock cycles away from your real needs. Slowing down and interrupting the functions of your system potentially breaking things. This along with adding attack vectors for other nefarious actors to penetrate your system and take full control.

You are correct I do have a choice not to use their poorly implemented code. And I definitely will never use it. The final point I will add is if this were to happen it becomes a slippery slope for other companies to add their own kennel level "security" code. All you have to do is look at any other system. Next thing you know the last light of OS freedom will be extinguished.
