FHE might allow arbitrary computation, but I use most services because they have some data I want to use: their search index, their knowledge, their database of chemicals, my bank account transactions, whatever.
So unless Google lets me encrypt their entire search index, they can still see my query at the time it interacts with the index, or else they cannot fulfill it.
The other point is incentives: outside of some very few, high-trust high-stakes applications, I don't see why companies would go through the trouble and FHE services.
