&quot;Who can enforce the copyright and licence?&quot;<p>The answer is only the owner of an <i>exclusive</i> right of copyright has standing to sue. So any of these open source projects that have no copyright assignments would have trouble suing. But in practice, who cares. Unless you want to sue people, it literally doesn&#x27;t matter.<p>The only folks who often care about suing are those who are trying to enforce certain types of share-alike licenses (GPL, etc) because they are ideological.<p>If you are using Apache or BSD, you probably aren&#x27;t suing folks because you are fine with them commercializing it or doing whatever with it (and if you are using these liceneses and aren&#x27;t okay with that, you may want to reevaluate your life choices)
