The quote isn't talking about FISC warrants. Its talking about regular Article III warrants.
What's deeply ironic about the outrage here is that FISC was created as an extra layer to safeguard privacy. FISC warrants give law enforcement officials permission to initiate an investigation, not to access information that would otherwise require an Article III warrant.
Don't conflate FISC warrants issued for criminal investigations. FISC is barely even a speedbump when it comes to this sort of surveillance.
