About the Opera web browser

Hello everybody. Now, if anybody reads this i want to ask you something, PortableApps.com now excepts {Freeware} software right, well if so it showed on the wikipedia that Opera’s license is Proprietary (Freeware) with open-source components. Now, does that mean that Opera is actually Freeware, well if thats true and PortableApps.com now supports Freeware software, i thought that Opera would make a good portable app and i would like to request it, but only if i’m not wasting anybody's time. Right now, i came across 3 different browsers, the original, a portable version called Opera@USB and another portable version called OperaTor, all 3 of them can be downloaded for free. I want to request this because i’ll like to see a portableapps version of it.

And that is all and remember this is only a question please don’t take literally, and thanks for your help.
