Unless you are getting the source code with your purchase, you aren't owning it in the traditional meaning of ownership. They are all licensed purchases in the closed source world. Otherwise there would be no need for EULA agreements (doesn't matter if one bothers to read them or not).
In that sense, I do agree with the OP. When it comes to commercial products that are closed source, none of us really own them at all. Period.
Symatics. I own the right to use the product forever. They can't take that away from me - they can't disable my license, or remove it. I'm paying to use the software from the day I buy it, to the day I die... In that sense I do own it.
This is the digital age. Any car purchased in the last 10 years has software on it. You don't own the software, just the right to use it - does that mean you don't own your car? Or cell phone, or computer, or printer? Everything electronic uses software you don't "own".
If you want to be technical, it's like artwork or fonts. You own the right to use the product. So while the product itself is not yours, you still own the rights to use it forever.
