I think because it can distract a person from their avodas Hashem, attach them to technology, and cheapen relationships. Years ago the rabbanim in eretz yisroel asured it, and having texting is still not so accepted amongst the frum there. It IS a very wholesome way of life.
My personal hashkafa is that it should be treated the same way we look at all gashmiyus – a helpful tool to serve you, yet a dangerous master.
Learn to use it productively and for the right things. Be honest and self-aware. Don’t waste time and don’t let it replace real communication. With that in mind, texting is not bad.
