Many coins are 1on1 copies (some with small changes), ETN isn't a simple copy from Monero.
ETN is an very tweaked monero.
You can't compare it with other coins what has forked. Also the diff was very, very high because of al the asic miners. Other coins also didnt had this problem.
If it was just an copy from monero i would totally agree with you, however it is not a simple copy. And problems are there to be fixed

Even more reason than to have a good dev team and experts.
Just in generally: I personally have my problems with projects that have good marketing teams, 1000 advisors, make daily a video, have mods/admins on
20 channels but only 1 dev. (Just as an example).
In my opinion the technical advance must be priority, than everything else. Just as a side note as i see many projects focus a lot on marketing but fail to
deliver/develope technicaly..... The best example for that is Verge, hype and always back to the roots.... I have still believe in this project, but as we are
on day 6 now without transacations (maybe even without accepted blocks?!) i strongly advice to investe more on the technically side.
Dont let the current situation fool you; trust me.
They have a patent for Instant Transactions Tech. They hired a Monero Dev and have other blockchain experts.
They are not the "deer in headlights" regarding tech as they are preceived to be.
