They're literally using Lightning for payments right now in El Salvador. They didn't do this without having local projects already. Bitcoin Beach (https://twitter.com/Bitcoinbeach) made a lot of this happen.
I don't think it is. Startups fail at tremendous rates and are well known for playing it really fast and loose, even if some of them are wildly successful. Not exactly something I'm interested in relying on for finances until there is a much longer track record.
The cost and complexity of opening channels for users is prohibitive. Any widely adopted solutions will therefore be custodial. Might as well use PayPal.
There's a big difference between a solution which requires you to use a custodial service, and one which gives you the option of non-custodial service - the latter allows for a much greater ability to hold custodial services accountable, by opting to self-custody, without forcing you to change your payment medium in the process.
Sure, I just installed it and its saying some impenetrable stuff about a swap address that is not controlled by my wallet and deposits will be converted to Lightning channels.
