The IRS isn't comparable to this case because there's 2 entities at play, the Irish tax authority and the EU's.
I'm not too familiar with how exactly it works in the US so excuse the probably poor example, but this is more like Texas deciding that they want to attract businesses by saying they'd lower taxes a bunch. They say to the IRS "Hey, we're going to be lowering all corporate taxes to 15% across the board, is this good with you?". The IRS says sure, not knowing that what Texas is actually doing is making sweetheart deals with companies like Apple to have them pay a tax rate that is basically 0 (0.005% as is the case with Apple in Ireland).
This tax-free opportunity is only provided to a single company. The lying here is relevant, because Texas explicitly told the IRS they'd be charging every business at 15%, only to then make a special deal with Apple that's unfair to all other businesses and Apple's competitors.
A decade later (more like 2 in this case), the IRS investigates and sees there's been a discrepancy between what Texas said they'd be doing (taxing them at 15% like they said they'd charge every business) and what they're actually doing. So, the IRS says that's not allowed, and that Apple now owes Texas that unpaid tax income whether Texas wants to take it or not.
Texas doesn't want it because it makes them look like they're double dipping. Apple doesn't want it for obvious reasons.
