Just going by "feel" without rigorously analyzing why it feels this way, my personal answer to your question is that the sqlite encryption extensions feel very much like LiveShare and not so much like Remote. Remote feels to me like a major part of the product that MS advocates without differentiation. LiveShare feels like a neat add-on that's a nifty alternative to several other similar things.

Similarly, the encryption extension has many alternatives and I've never heard Dr. Hipp advocate using it. This thread is the first I've heard of it, and I've heard of alternatives before. Where I knew coming in about Remote and LiveShare based on promotions from Microsoft.

That's just an explanation of how it "feels" to one reader, not any kind of careful analysis or sweeping statement.
