&gt; &gt;&gt; I think this comment by patio11 is very relevant here:<p>&gt; &gt; &quot;We don&#x27;t donate to OSS software which we use, because we&#x27;re legally not allowed to.<p>&gt; I routinely send key projects, particularly smaller projects, a request to quote me a commercial license of their project, with the explanation that I would accept a quote of $1,000 and that the commercial license can be their existing OSS license plus an invoice. My books suggest we&#x27;ve spent $3k on this in 2015. My bookkeeper, accountant, and the IRS&#x2F;NTA are united on this issue: they don&#x27;t care whether a software license is OSS or not. A $1k invoice is a $1k invoice; as a software company, I have virtually carte blanche to expense any software I think is reasonably required, and I think our OSS is reasonably required.<p>&gt; This shoots red flags, so I&#x27;d like to share:<p>&gt; Anti Money Laundering:<p>Negotiating a price isn&#x27;t money laundering. If you have records of your customers, then you have proof you weren&#x27;t laundering money.<p>&gt; Anti-terrorist financing:<p>If you do what SQLite does (they either sell their software for $1000 or give it away gratis), then this isn&#x27;t an issue.
