For 30 years I have been using permanently both FreeBSD and Linux, because they both have strengths and weaknesses.
I am using Linux on laptops and desktops, where I may need support for some hardware devices not supported by FreeBSD or I need software compatibility with certain applications that are not easily ported to FreeBSD.
I also use Linux on some computational servers where I need compatibility with software not available on FreeBSD, e.g. NVIDIA CUDA. (While CUDA is not available for FreeBSD, NVIDIA GPUs are still the right choice for FreeBSD computers when needing a graphic display, because NVIDIA provides drivers for FreeBSD, while AMD does not.)
I use FreeBSD on various servers with networking or storage functions, where I value most to have the highest reliability and the simplest administration.
I believe it's an effort to promote Linux, to get more market share.
Linux users aren't interested to see potential adopters go for BSD instead of joining their ranks.
On every forum, every discussion, there is at least one guy saying he runs that game on Linux, or that other OS is somehow inferior to Linux, or this problem would never happen on Linux...
For some reason, every time FreeBSD is put in a positive light there is always a lot of Linux(-only) users who has to put FreeBSD down.
I don’t understand why. Would be interesting to understand this psychological phenomena.
