No, the problem is that the altimeters didn't meet spec. These altimeters are NOT supposed to be susceptible to these frequencies. However, people cut corners decades ago and now it's being found out. The FAA should have told the airlines "You have N years to get these replaced. Start now." But they didn't--because they're in the pocket of the big aerospace companies. Well, so the FCC rolled it out. Now the FAA and the aerospace companies have to deal with it.
