The ETN white paper says: "See the Electroneum Technical White Paper for a technical description of how the Electroneum memory bound algorithm for proof of work is specifically designed to promote CPU mining, which average users have access to and reduce the heavy industry approach (...)"

We should all care when a project steps away from their white paper.

However, now I'm glad they kicked us average users and small GPU miners from their blockchain. Otherwise I would still be mining and holding ETN, loosing money at the end of the day (since the price of ETN is sinking reaching all time lows).
