Yes, many companies are guilty of it. It comes down to ego inflation. "Engineer" lends an air of prestige and esteem, but it's a title that's undeserved by most who use it in modern times.
Of course, this gets severely down-voted because many people on HN and similar sites think of themselves in this fashion, and their ego takes a hit when they run across a comment such as mine.
I don't think it has anything to do with ego inflation.
To me "engineer" evoques a specific methodology and state of mind that is shared by all engineers, whether they build bridges, sewer systems or software. It emphasizes that your job is to create solutions to real-world problems - and that writing software is just one part of that job.
