Yes and no.

the solution to the problem was the correct one, they just forgot one important detail.

TELL THE USER!

As a result, plenty of people, (including myself) noticing their two year phone starting to slow down quite a bit, decided to upgrade to the new and shiny model, instead of just replacing the battery, because who would have known that was the problem?!

Yes, there should've been a "your battery has degraded" alert with information on implications and how to fix it. Apple was wrong to do it silently and without warning.

They did issue a mea culpa and free replacement coverage in response to that criticism, but it took a while.

Well, they did, in the software update notes for the version that introduced this change. I do agree that they could (and should) have been quite a bit more prominent though.
