I defrost thoroughly, let it drain in a strainer, then squeeze by hand and think of it as cooking -- a thing to be enjoyed.
Maybe I don't use large enough quantities frequently enough too see it as unpleasant. If frozen spinach has a reason for being, it's how much easier it is to squeeze out than fresh.
An old trick is to put the drained, defrosted spinach in a towel, make a "bindle," and twist the neck until the pressure forces the moisture through the towel. The downsides are leaving a good bit of spinach on the cloth (especially if you're using chopped) and permanently staining the towel. Not that big a problem if you started with a bright green rag, I suppose.
If chopped spinach in bulk is too much onerous, use whole leaf, dry it in your spinner, then chop in a food processor.
