I think the last time I had bought any commercial software for
FreeBSD, it was OSS drivers about 20 years ago. Not sure there's been any since.

I doubt the browser vendors make a path for hostid to show through,
when there are a million other things that browser fingerprinting can
capture and use.

Ie. are you unique enough? https://www.amiunique.org/

There's so much other data to be used that is pushed through the browser
allowing fingerprinting.
