I use ligatures in atom and they are 100% aware of context. I disable them in contexts where they don't make sense e.g comments and I disable them on the line the cursor is on.

I've not had any issues. The => ligature looking like the right arrow character is just like a cyrillic A looking like a latin A - it's a problem that never manifests itself.

The author has a very subjective opinion that they try and present as fact.
