Why Does EA Force Game Pass PC Members to use EA Desktop?

EA should really have the option to port EA Play with Game Pass to Origin as well as EA Desktop. It makes no sense that EA is forcing everyone to use an unstable, "Beta" version of a launcher when they already have a pre-existing, much more stable, and reliable launcher. I get that they want it for testing, but leave that to the people who volunteer to contribute their feedback on their own accord rather than forcing everyone to do so. EA Desktop is extremely buggy and severely affects my games. First off, EA Desktop does not create Desktop Shortcuts despite mentioning it when you launch a game from the app. So you will have to literally go into your programs folder to create a shortcut for every single one of your games you install through EAD, that is if there is even a shortcut for the game in the file location (*coughFallenOrdercough*). You also have to reinstall the game -Which you also can't do through EAD by the way, only through Windows Program Manager- if you want to change the language of the game if it doesn't have the option to do so in-game, which is part of the removal of game properties and advanced launch options that I found very useful in Origin. On top of that, I've been experiencing network issues and severe performance drops ever since I started playing through EA Desktop. Trying to launch PvZ: Garden Warfare takes forever to launch (like 5 minutes later at least). And once I exit the game, I have to restart my PC or relog back into my user in order to launch the game again because it will not launch again after you've quit the game once. Star Wars BF2 has been experiencing network connectivity issues and mouse/UI bugs ever since I started playing it through EAD. Trying to connect to the BF2 servers with the "Connect" button is a trial and error process, and I have to disabled Discord in-game Overlay in order for the mouse and UI to function properly. I also experience severe FPS loss for every game I have installed through EA when that never happened through Origin. And no, it's not any issues with my system because I run EA Desktop with my games across three PCs that I own, and the problems are consistent for every single one. Really, it's upsetting that we can't port our Membership to Origin, or at least have Origin detect that we have a Game Pass account linked to EA. Why is this?
