>What if they had access to the IP that is currently locked away by the likes of Apple/Google? What if anyone who wanted to replicate a good design (and improve upon it) were able to do so without restrictions, or fear of lawsuits?
Then nobody would invest any money in releasing stuff and we would still live in the stone age.
None, they are doing it just for the show; understand that they probably did this analysis for free, so in exchange, they get this ad/article where they have to look very professional and methodical.
You misunderstood. I am affirming, they have used Photoshop to insert text in that screenshot, and they have mistakenly used another font, Roboto. It's easily noticeable, as it's narrower, and some glyphs (like that "g") are different.
No, it's not subpixel anti-aliasing. It's a completely different font. It looks like Roboto to me, while the rest of the email is written using Helvetica.
DOM manipulation, of course. But not everybody knows about it. So most people default to Photoshop, which is what these people did.
That email is fake: they have forged the screenshot. In the first paragraph you can clearly see how the typeface changes to something different (starting with "enterprise-grade")
