I think it’s just a matter of businesses perceiving the potential revenue increase not worth the overhead, combined with the resulting slow growth and development of ecosystem of service providers. Running an independent node does take some management above that of a normal bitcoin node and merchant tooling and open source integrations are still coming together (though there are some good and dependable options). A merchant will need to keep an eye on their incoming liquidity, or use a service provider that does. That being said, once you’re actually using it it’s a great experience, and for the individual enthusiast running a node can be great fun. One service provider is Bitrefill, where you can buy Steam credits (and much else) over Lightning with a throwaway email faster than it takes for me to dig and type out a credit card out of my wallet or go through the SMS2FA BS of whatever virtual credit card-supporting bank I can find in the country I happen to be living in. Just copy and paste an invoice or scan a QR, depending on your wallet interface. I do hope we see Lightning support in Coinbase Commerce et al soon. Unfortunately BitPay, one of the oldest and I think the most widely used payment service provider for Bitcoin, has become pretty much unusable as of lately and even if they did add lightning support it wouldn’t be interesting.
