>EncroChat sold encrypted phones with a guarantee of anonymity, with a range of special features to remove identifying information. The phones themselves cost roughly £900 (€1,000) each, with a subscription costing £1,350 (€1,500) for six months.

That's a pretty pricey for what's basically a chat app. Is there a reason why they were able to command such a high price even though there are plenty of free/open source solutions on the internet? Marketing? Trust? Criminals thinking more $$$ = better?
