Depending on the company’s policies you may be able to install FOSS software. Outside of the other comments so far, looking at a problem differently may provide different insight.

The downside is that you will likely miss out on integrations provided by the proprietary software. Also, your company’s IT may not appreciate your experimentation. I had one coworker dual boot their computer to Ubuntu, which eventually broke the install. It was shortly after that that the company began locking things down tightly.
