Zombified piglins can control a strider to be able to attack the player when antagonized. The only way a player can control a strider is by using warped fungi, which the zombified piglins don't have. So the striders should not be able to be controlled by the zombified piglins.
Since 1.16.2 Pre-release 2, zombified piglins now spawn on top of stiders with Warper fungus on a stick in hand. While this is a partial solution, summoning a strider using
/summon minecraft:strider ~ ~ ~ {Passengers:[{id:zombified_piglin}]}still allows the zombified piglin to control the strider, despite having no warped fungus.

I don't agree with U. Baby Striders should ctrl who is ridden by it without Warped Fungi, I think they just acted like the Father & son or so.
Please change the description, because 1.16.2 pre-1 change, the zombified piglin spawn with warped fungus on a stick while riding strider.
It appears that all mobs can control saddled pigs and saddled striders. Pigs are already covered at MC-177995.
