<p><font face="Helvetica, Arial, sans-serif">Hi guys,</font></p>
<p><font face="Helvetica, Arial, sans-serif">As a distributor of
free fonts and also as an avid Linux user for over 20 years I am
in the process of writing an FAQ regarding the <a
href="https://www.gust.org.pl/projects/e-foundry/licenses">GUST
font license</a> and I am hoping someone here could give me
feedback by pointing out possible mistakes or help formulate a
better more precise answer?<br>

Most likely yes, but not 100% reliably. Even if possibly all
authors of GFL licensed fonts may have intended to allow
embedding in portable digital documents, the GUST font license
is unfortunately a bit ambiguous. For sure, fonts licensed under
the GUST font license (GFL) can be used freely and restrictions
only apply to<span> </span><a
href="https://www.latex-project.org/lppl/lppl-1-3c/#conditions-on-distribution-and-modification">modification
and distribution</a><span> </span>of the font files
themselves.</p>

widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px;
white-space: normal; text-decoration-thickness: initial;
text-decoration-style: initial; text-decoration-color: initial;">The
actual question then would be: "Is embedding a font into a PDF
or ebook considered a modification of the font?" While
technically this can be the case, as some bits and bytes may be
altered, the intended visual outcome of using the font remains
the same. Also considering that the font is not intended for use
outside of the created document, distribution of the document
does not have to be viewed as a distribution of the font.</p>

text-decoration-style: initial; text-decoration-color: initial;">The
GUST font license (GFL) does not explicitly depict embedding, so
the license could raise questions among technical savvy users
and interpretation of the license becomes a matter of opinion.
