The original article article URL before the change to avherald contains a post that addresses this: https://www.pprune.org/showthread.php?p=10450572 https://www.pprune.org/showthread.php?p=10450572 Obviously we'll have to wait and see what the actual story is, whether this is really old bad tribal knowledge, and if the operating manual contradicts that, and whether pilots are getting the proper training and consistently applying it in practice. I'm an opinionated and biased pilot and former flight instructor, but not an aerodynamic engineer. Spoiler extension does not increase the effective angle of attack of the wing, whereas a dropping aileron does. And therefore off hand, and without benefit of an Airbus type rating, I don't really care if the actual control surface is a bit of right spoiler instead of left (down) aileron, all I care about is that the windward wing does NOT lift off first because that will foul up the ground track on takeoff, and that's simply not proper technique.
