If you think a platform is responsible for what their developers do with it, then I understand. However, Kape was never directly involved in adware other than providing SDKs that let developers create positive and negative things.

To say Kape was involved in adware would be akin to saying the Wright Bros killed millions of people - because they made planes which people used to kill people (which is simply untrue). Even the original article notes this ever so briefly so as not to show Kape positively.

Thank you for your trust until now, and given the long track record and relationship, I hope you can verify my statements as well.

Our future work will always be the same work we have been doing, so whether now or later, I'm confident we will re-earn your trust again, and hope you'll give us the opportunity.
