I'm glad you mentioned this, I was just about to make a post about it. I didn't see the PCG article for some reason, but I saw this one on The Verge:
EA’s new PC app is here to replace Origin - The Verge
The only games I had on Origin were my Mass Effect & Dragon Age games, and I never really liked the Origin Client, but I really had no choice. There wasn't much of a "community" there as you'll find on Steam, and getting to the forum section was a pain. You'd click forums, have your browser open up the forum page, login (again), then click some more to get to the forum you wanted. Way too many clicks, and when you got there, nobody is home, or at least very few current posts.
Fortunately, when EA/Bioware games became available on Steam (2 or 3 years ago?), there was a big sale and I was able to repurchase the Dragon Age games with all DLC content & ME Andromeda for very little cost, and that cost was worth it just to have them on Steam. Later, I purchased ME Legendary to replace the original 3 ME games. You do have to have to be logged into the Origin Client running in the background, but it was pretty painless, only a slight delay in launching EA/Bioware games.
The reason I mentioned all this is because of a post in the Steam Forums for ME Legendary, that if you opt in to EA Play, your EA games may not launch on Steam. At least currently, though I'm sure...well no I'm not sure, but hopeful, that that will be corrected. As EA Play is still optional, if you own/play an EA game on Steam, I'd advise waiting.
