I was curious about "for a while" and it is apparently 16 years (2009 commit with message "license.txt" https://github.com/Jetbrains/intellij-community/tree/4d9912f0a51d09019b6fe5fe85d441738f0e207e https://github.com/Jetbrains/intellij-community/tree/4d9912f... ) and the PyCharm Apache 2 release seems to be a lot harder to actually track down but https://github.com/JetBrains/intellij-community/commit/e0d025da15217c6dbec279f5cb3ef584b373f145 https://github.com/JetBrains/intellij-community/commit/e0d02... is cited as "initial extraction of python-community module (for now with a few cyclic dependencies)" in 2013
