Association of Catholic Priests is a heterodox/ internal anti-Catholic group, so their elevation of a worldly concern over the care of souls comes as no surprise.  (Their name is misleading.  They're at least as much of a fringe organization as SSPX and their leaders have been repeatedly censured by the CDF.)

People need what deacons can provide (and would that canon law changed so that deacons could hear confessions!)--there should be more of these men.  But those like the ACP who do not share the Catholic view of the Sacraments as divine ordinances and ordinary channels of grace naturally do not see the ministry of the permanent deacon as worthwhile.
