Yes, of they have a responsibility to study the legality (and morality) of what they are investing in.  However, I&#x27;d withhold judgement on the investors until we have reason to believe that they knew they were investing in this.  Their last funding was in 2013 [1], and they have produced several apps.  It&#x27;s very possible  that their investors don&#x27;t know about this act.<p>[1] <a href="https:&#x2F;&#x2F;www.crunchbase.com&#x2F;organization&#x2F;highlight#&#x2F;entity" rel="nofollow">https:&#x2F;&#x2F;www.crunchbase.com&#x2F;organization&#x2F;highlight#&#x2F;entity</a>
