Modern fonts are vastly more elaborate pieces of software than what people tend to think they are [1], and you get what you pay for. If you just need 56 letters, get a free font. If you need full Unicode Latin support, with proper kerning between each of the thousands of possible pairs, with ligature substitution for hundreds of tuples, not just for one language but several, with compositional repositioning for languages that require it, and alternate glyphs based on initial, median, final, or isolated letter form, and so on and so forth, then dollars will get you what free cannot.
Everyone can make a motivational jpg, but you need to pay a skilled digital artist to create a unique well composed new work. In the same vein, anyone can make a font, but you'll need to pay a skilled typographer (or foundry) if you want a well designed, feature rich typeface.
font-variant-numeric: tabular-nums
For fonts with the support coded in, this variant means numbers in tables will line up in your font without outright switching to a monospace font. Beyond good glyph design, as the parent mentions, there's a lot of work to craft a professional modern font esp. the more of the Unicode language space it spans.[1] https://developer.mozilla.org/en-US/docs/Web/CSS/font-varian...
This is also a US-centric comment. Other jurisdictions have differing rules to cover fonts and typefaces. In the US, however, it is fully legal to lawfully acquire a physical font specimen, scan that font, and do what you wish with it.
Caveat: IANAL
I can't imagine who would pay for this particular font :/
That's not a consideration for everyone, admittedly, but an incredibly important one for those who _do_ have to take it into account.
Gorgeous font, bit of a bugger to build but once you get it working hours of tinkering ;)
The condensed look and lack of interlinear spacing of PPro are a nice bonus, not that there aren't other condensed fonts. I suppose for intl use PPro might be nice too since it has 9000+ glyphs, and the dev is still adding more.
So that's effectively asking why Arial doesn't violate Helvetica's copyright.
The names are trademarks, so you can't copy them exactly, but you can use suggestive alternates. Palatino => Palatable, for example. TeX Gyre Pagella is a very nice version.
The code is copyrighted, so you can't copy the code exactly. But -- you can rasterize a font, print it, scan it, vectorize the output, add your own hints, and now have a clean re-implementation. The shapes of the letters are not copyrightable.
