I wouldn't necessarily consider it a scam just because the concepts are similar and the names are similar. If you have proof of scam or further information, please share it...

The Viuly project has been announced for quite some time....
From what I noticed, View.ly was announced after the Viuly announcement was made.

So, it really depends on which side you support.
Apple/microsoft/mac are very similar companies with similar objectives but are legitimate projects.

Just because it presents competition to the project you support, doesn't justify calling it a scam.
