Simplify requirements and the tooling and technologies simplify alongside.

F/OSS is not the panacea its advocates claim it to be. I mentioned collecting bizarre compiler bugs. GCC has a huge presence in my collection.

And this ignores the fact that F/OSS often has no presence whatsoever in entire industry swathes. F/OSS, for the most part, with some exceptions, lags behind the technology curve when it comes to bleeding-edge tech. This is sometimes the fault of vendor shenanigans (I’m looking at you here, Altera and Xylinx), but often it’s just the problem of a very specific problem domain with very few eyes willing to work on it as a hobby.

Because there’s not enough hours in the day to link to trivially-searched information to counter every ignoramus that thinks their opinion matters anyway.

I’m not their Google/Duckduckgo/Bing/Baidu/whatever stenographer. Google et al are a few keystrokes away. They can do the legwork themselves.
