Yes I've been changing "utilise" to "use" by hand in Wikipedia for many years. When I read "utilise" I hear Homer Simpson in a top hat trying to be posh.
Perhaps some people find monosyllabic words embarrassing. Another word sometimes misused instead of "use" is "leverage", and you'll often find "ubiquitous" in the same paragraph in engineering/marketing contexts. But "leverage" should not always be replaced with "use": sometimes "exploit" would be a better alternative. And "leverage" has a proper meaning in finance, of course.
