Not condemned at the time apparently. Symbolic couples, Greek and Celt, were entombed alive after the Battle of Cannae for example.
They weren't formerly banned until 97 BC, a few generations after the end of the Punic Wars and then there were exceptions not considered 'sacrifices' as such. Cicero was writing around the time of the ban, not when such sacrifices had been common. Livy and Pliny were even further removed.
While not formerly sacrifices, deaths of gladiators were still dedicated to the Manes and Vestal Virgins and especially 'ex-virgins' were still entombed alive on occasion for the 'benefit of the city'.
