Can I sell MetaMask?

Excuse me, I'm a bit confused about something. Could you please clarify for me? I've heard of MetaMask, and I'm wondering if it's possible to sell it. I understand it's a crypto wallet, but does that mean I can't transfer ownership or sell it to someone else? Could you explain the process or the limitations, if any, in selling MetaMask? I'm just trying to understand the ins and outs of this cryptocurrency world better.
