It's like the "pls no pirate" messages on DVDs that pirates never see.
I've never once had a license problem with Omnigraffle and I've been a paying customer for 10+ years.
Too many companies use emails as a metric over sales. Selling someone after the fact is much harder and no VC is caring about email only signup numbers.
There are plenty of libraries, utilities etc. that haven't seen an update in years, because they're done and there's nothing more to add or take away.
I would have followed the project if it was more active, but no commits in 21 days for master branch, 28 days for develop branch and a diff of 246 commits between the 2 branches leaves me perplexed.
The website doesn't even list the features of the tool. "Wireframing" is very broad. You can create wireframes in PowerPoint if you need to. Other functionality, like generating a clickable multi-screen prototype that can be loaded on a mobile device or shared with a client, that's more advanced functionality that's required for corporate design work.
Also why not use standard identity providers?
Also, why not make your front page actually say something useful? There are lots of words, no real content. Also, the project tool seems to indicate it's been dead for 4 months?
