Could you please elaborate on why washing your stuff inside out helps? I would think what's inside rubs against the other side of the inside, and wears out just the same.
Assuming a heterogenous mix of clothes where some of them have external features that are more damaging to other clothes in a washer, and some have external features more prone to damage, inside-out helps even with front-loaders.
Of course, much of this can be addressed by separating different types of garments, but that can be a lot less resource and time efficient to do really well.
Washing inside out doesn't help with front loading machines. Top loaders with agitators will damage the fabric though, and washing inside out will help there.
