Heavy Linux user here, and I'm more than willing to pay for good software that provides a vital service for me. That being said, there definitely is a fine line, as if the software doesn't provide value over a similar oss/foss tool, then it's not justifying it's price. PyCharm is a well-know paid software that has a strong Linux/OSX presence, as well as almost all other JetBrains software. Sublime Text is another.
