I start to see it more as some sort of an economical attack against Bitcoin by not taking advantage of what SegWit has to offer. By this time we could at least sit on 50% adoption, but instead, services are holding off. Services are the one needing to spark SegWit adoption, because if they don't, what incentive will people have to adopt SegWit? If Coinbase starts with SegWit, I am sure it will just be a matter of months before other large entities in this market will follow, because that's how it works. LN at this point is just being tested here and there, but that doesn't say anything about an actual estimated date we'll see it roll out.
It would've been helpful if its launch hadn't coincided with the bull run from hell which must be pushing services to the limit, but I'm pretty sure services such as Coinbase and Bitpay are holding off mainly to make their political points and pile on the pressure. Bitstamp were right on it. Shapeshift now has it. Kraken has it internally. It's getting there slowly.
I'm slightly shocked the Core wallet wasn't ready to roll immediately.
