The VGG License 2.0 is pretty confusing. It offers two licenses: VGG License 1.0 for commercial use (with royalties) and Apache License 2.0 for personal use only. But if personal use doesn’t involve making money, why add the Apache License? The original VGG License 1.0 could cover both personal and non-commercial use without royalties. Disregarding whether the royalty fee makes sense, the dual licensing setup just seems unnecessary and complicates things.

Dual licenses, or triple licenses are common in some open source software. Maybe more rules should be presented to make the dual licensing more clear?

Yes these licenses are common, but the dual licensing with essentially the same effect as a single license seems fishy and suggests there might be something hidden. Just my two cents.
