By skyforbes I got downvoted on my previous Post for bringing up the Discussion that Linux, namely the Linux Kernel needs more protection & pushback as time goes on from AI & to keep it open source, especially after Linus dies. This same ignorance occurred when it was suggested that Linux will require antivirus software going forward into the future the more it becomes popular and open to cyber attackers.
Also, to people falsely claiming that Unix was ever free, it wasn't. That was the entire reason why Linus wrote the Linux Kernel to make it open source which was distinct from the close sourced nature of Unix. BSD is also distinct from Unix in the same regard. They are "Unix like", but Unix isn't & wasn't open source.
And lastly, just because software, companies, & infrastructure uses the Linux Kernel, this doesn't translate as "Linux is commercial". It simply means, they used the Linux Kernel for their project/product. That's for the posters who defend the claim that "Linux is Commerical".
