The assumption here being that the integration of the now disused product into the parent product (Mailbox into Dropbox) has no potential to reveal the internal workings of the parent product <i>e.g.</i> APIs or data structures. Or that those techniques would only be applicable to competitors <i>in that market</i>. Both are convenient for your argument, but there&#x27;s no reason to think that they&#x27;re correct. Moreover, there&#x27;s no reason for a risk adverse company to accept those assumptions.<p>My point was to challenge open source cheerleaders to actually give a reason beyond their own gain for why a company should do this. Instead, we have blithe dismissals and narrowly constructed hypotheticals built on optimistic assumptions.
