Just like "engineer" is a reserved term in many jurisdictions, "open" should be too. At least in our industry.
If a bakery wants to call itself "open", so be it. But if software calls itself "open", it had better be open.
OpenAI, OpenRouter, OpenArt, OpenGov, OpenWeb, OpenText, ... this is all malarkey.
The only instance where "open" isn't trying to pose as open source is when it's a verb or adjective coupled with a noun used in a well-understood colloquial manner, eg. "OpenDoor", "OpenTable".
OpenAI implies open source AI. Look at how hard this "open" company tries to regulate open weights.
OpenRouter implies open source routing. Their platform isn't open source at all, and a lot of the specifics people will grow to care about are entirely proprietary.
Don't even get me started on OpenGov, which is a complete travesty.
These are such bold-faced lies.
When AI was new, I definitely got fooled by "OpenAI" and thought it was an open source style AI company. Boy was I wrong there.
The straight abuse of language lately has become quite frustrating overall, but part of that gets political and I'll stray away from that to not get too off topic. When I see these words like "Open" used in the title so often, it just makes the word feel like it's tied to a new fad, and makes it harder for me to trust projects with those names.
