That is an interesting idea, that I certainly hadn't thought of - though I guess a phone would only correct a word to "Thelema" if that word had been encountered at least once. I know Thelema is the name of a god, but is it one associated with something satanic?
There is nothing inherently satanic about Thelema or Crowley, unless your POV is doggedly Christian. In essence it is based on the notion that if you find and follow your proper path in life all will be well. Its more elaborate than that, of course. There are claims that it has a deep foundation, but I suspect that is BS and it is no more than a flash expansion of Mills' proposition about liberty. At the time that would be a fresh and radical idea. The essential problem, for me, is that for the Thelemite philosophy to work it requires a very deep level of self-awareness. Take part of the Thelemite creed that says "Love is the Law, Love under Will." WTF does that really mean? You can decide it means what you say it means, which is what most adherents seem to do - in which case it is no more than a license to do pretty much as you please (this is the same problem the Wiccan creed has). This why I suspect Crowley appeals to power hungry psychopaths and other arseholes (assholes to Americans) who love wealth and influence.
In reality, discerning the nature of Love, Law and Will is probably a life time of deep thought and meditation - before you figure you can act in the confident knowledge that you understand the creed. That is not something you will find any Thelemite into.
