Fonts can't be copyrighted. They didn't agree to any EULA. All they need to do is convert the font to some other format, and they are legal.
And BTW, this line is ridiculous: "It must be ensured that the Font Software cannot be fully or partially extracted from said documents".
It's possible to embed a subset of the characters, and that's what most require. But to prohibit even a subset? That means you can not use the fonts for any electronic documents whatsoever unless you convert them to bitmaps, which means they are almost useless for PDFs.
I personally would never buy a font with such a restriction unless all I made was print.
BTW, if you want to be legal, just download (pirate) the font file, and convert it to some other format. You never agreed to a EULA, and fonts can't be copyrighted (only the original file can be).
In theory they could complain about the original pirate act, but they would have zero evidence, and any subsequent usage is legal.
Mechanical conversion from one format to another doesn't defeat copyright protection. If you write a book in English and I translate it into French (a change much more fundamental and much more creative than you're proposing), that doesn't entitle me to publish it without your permission.
The shapes of the glyphs are not protectable. The font file is considered to be a computer program, and is protectable as such. Converting it to a different format doesn't get around copyright any more than compiling a C program does.
As gjm11 noted, the font software is copyrighted (as I understand it), the actual glyph design is what can't be copyrighted. If you are still distributing a portion of the copyrighted work (the font software), that would presumably be a copyright violation.
I don't know the actual extent to which copyright protection covers font software or derivatives. There is at least some related case law, but I've only skimmed it and am not an attorney.

Font licenses always specifically address PDF embedding.
