Use of "open source" in website name

[Beth]

Hello,

I have a question regarding the use of "open source" in a website name.

A web developer I know wants to register an available domain
"www.opensourcesomething.com", this site has nothing to do with
software but the site is a commercial, for profit venture.

I've indicated that I thought it might be inappropriate to use the name.

Is this a questionable use of the term "open source" ?

My apologies if I've posted to the wrong list

Best Regards and Thank You,

Beth
