I have found not all open source to be the same in the modern era. The FOSS of yesteryear has been replaced by a lot of projects aimed at enterprise where the FOSS offering is the "free demo." This may have been novel and clever of the original pioneers of the practice, but there's a lot of cargo culting going on.

The worst offenders release the source but with gotcha licensing, wait for the enterprise to use it, then detect their usage and go in demanding payment or be sued. This happened to my team enough times to be a pattern.
