If the EU were responsible adults, they might have phased it in, and tried to be clearer about what constitutes penalty worthy ambiguity. (Right now, its a bit of a "we will know it when we see it" sort of thing). But what company wants to deal with the risk of some jack-booted dominatrix wannabe by the name of Andrea Jelinek, being able to mete out fines for up to 4 percent of worldwide annual sales? And based on some interviews and her snarky, "Fuck the rich" responses, she seems almost eager to build a reputation as an Elizabeth Warren man-and-business-hating wannabe.
So if you're big tech: you were targeted because EU's entrepreneur crushing taxes and regulations had guaranteed that all big innovations were created outside the EU, so now they want to smack them for being successful, and tell them how to run their business.

Sadly, many Europeans will blame the companies instead of the regulators. And that's how the Nazis rose to power.
1 Year Review
1 year in, and guess what happened: big tech used AI/ML, Facial Recognition and other techniques to get around the unenforced rules. While the smaller guys are unable to compete. That's what bureaucratic victory looks like: higher burdens of entry, less competition, and non-enforcement or selective enforcement of the law. Woo hoo! Thanks for that.
