Undoubtedly, The Lightning Network is a good solution for making millions of transactions, but it is an external technology designed for Bitcoin. Not many people use LN channels yet, but I see how its network is growing day by day.
It's not mainstream joe ready yet, which explains why the network as it is right now is small and cumbersome to use due to the lack of reliable clients. Funds are at risk and for that reason I'm happy they don't jump on board yet.
By the time Coinbase and the likes of it start to adopt LN, you can be sure that there will be a massive adoption boost taking place. The interesting part is how the big block camp will react to a fully deployed LN.
They can continue to block SegWit as much as they want, but when they do the same with LN they put themselves in such a losing position, that it will actually starts to hurt their core business.
