@michalsestak said in Commercial use of the Opera browser?:

(A) use the executable code version of the Software solely as installed on your personal computer;

IANAL, but looks like EULA is written by some NAL (not-a-lawyer) either. I would read this "pesonal computer" as PC - which usually means any single use computing device, but sometimes even terminal server 🙂 At your workplace, are you sitting behind PC screen, no?
IMO this statement is not about using PC for Opera, but rather about using your/any copy of Opera (executable) somewhat differently than it is installed, like binding its executable into different software package and promote that as your superbrowser or similar.

g. Snapshot: Opera’s browser for computers may include functions that enable you to easily take screenshots of content viewed through the browser. This feature is for your personal, non-commercial use only. You agree never to use the feature in any way that violates applicable law, or the rights of any third party, including copyrights.

IANAL again, this should mean that you agree not to take images from copyrighted works (which can be understood as illegal copying) and/or not sell any such images or use them in advertising materials and similar (which usally constitutes as commercial use). Or if snapshot functionality can be automated or scripted, then you should not create web pages 'snapshotting' automaton (and sell it or its results).

Surely some better worded (or explained) EULA would be preferred.
