He abandoned his young son
Several commenters argue that walking the globe for decades while his son grew up makes Bushby an absentee father. They say his inability to enter Northern Ireland doesn't excuse it.
Context and reconciliation matter
Others note that military rules barred him from Northern Ireland and that he and his son have since reconciled. They see the moralising as social-media peanut-gallery noise that drowns out discussion of the walk itself.
Logistics: visas and broken steps
Some focus on the practicalities. Visas were the hardest part, and he paused often, flying to his Mexico base and back to the exact spot he stopped, so the walk wasn't literally continuous.
