The Neocatechumate have gone way beyond simply blessing a few rosaries. The pope has repeatedly encouraged these "new movements" in explicit terms. And you might group "Opus Dei" under the same umbrella. No one is going to claim that the pope merely blessed a few of their rosaries.
And your issue with Opus Dei is?
Opus Dei is an entirely different matter. The Pope has made them a personal prelature of his own and has given explicit and sustained support to Opus Dei - by asking specific bishops to be more open to Opus Dei's ministry, etc.
Of course, Opus Dei is orthodox and the Neocatechumenate is heretical.
