You're not alone. I'm of the mind that it doesn't matter what the license, state of the source, or whatever, I'm here to get things done, not quibble over trivialities and semantics. When I can see the source for something, I call it open source. If the OSI has a problem with that, I invite them to explain to me how my definition affects their goals in any way, shape, or form.

I like the OSI. I use a lot of stuff that they endorse. My 3D printer is OSI certified (or whatever the proper terminology is). But I use my printer to solve problems, and it being open or closed source doesn't really matter, so long as it helps me solve problems.

I like the FSF. I use a lot of stuff that they endorse. One of the operating systems I use is FSF certified (or whatever the proper terminology is). But I use this operating system to solve problems, and it being open or closed source doesn't really matter, as long as it helps me solve problems.

I like Microsoft. I use a lot of stuff that they make. One of the operating systems I use. . .you get the idea.
