Won’t happen. Lawyers and idiots rule. Common sense doesn’t count any more.
So unprotected cells of the “big 4” will disappear from the legal markets. Chinese nonames will fill the void. Is that safer? I dare say not. Crazy wold.
Endorsing such beliefs, it may never happen. It's all about loving and enlightening.
If people wants something, let's serve them. We should patiently enlighten them into being fully responsible beings. And this is both towards the ones “below” and the ones “above”.
The big ones may also need help, lawyers need help. We need fairer legal systems, focusing responsibilities properly.
At least there are some chinese manufacturers starting to gain momentum, which is great (see the OEM behind the LiitoKala 26650s and the Soshine NCR26650s).
