IDE space is free. Copy and pasting a long string takes no more time or effort than a short string. What you stand to gain from shortening a name is trivially small compared to the risk of making a name too short, potentially leading many people to each waste time trying to figure out what you meant. The author's real problem is not about an excess of characters, it's that names are often long because they include redundant or irrelevant information. Still an incredibly minor issue, but there's some legitimacy to that. Better advice would be to keep names informative.
