most major metagame threats are not affected or absorb them (venusaur, tentacruel, every steel type ever made, any mon that floats), and the selection of pokemon that set them are extremely restricted, not to mention most of them have better things to do with that moveslot. there are some kinds of team that will, by good fortune, be weak to tspikes (certain sorts of offense) but it's vastly outweighed by the number that really don't care
there are a few places where tspikes are generally considered "viable" or even good, eg subroost kyurem + tspike cruel on hail, but they're pretty rare and generally you should not be using them.
