"Download applications from a trusted source"
Oh, that's great. Except it's apparently none of that - Opera has discovered Yahoo catalog's Software section, cca 1998:
"The software itself is downloaded from and offered by independent, third-party providers. By providing a link to software, Opera does not imply approval or endorsement of that software. The software is not investigated, monitored, or checked for accuracy, reliability, appropriateness, or completeness."
The large print giveth, the small print taketh away.
