Yeah, functionally it's the same. However I think it is a big perceptual change to be in line with the FUTO principle of "we want to make good software that is open and accessible, but we would also like you to pay us for it so we can continue this project sustainably." That's a bit of a contrast with the general open source approach of "I'm writing this software as a service to others, make a donation if you'd like to support my work."
Personally I think the move towards a more structured buy it if you can mindset is great. I've seen too many projects get abandoned because of lack of time and resources and then shift from developer to developer, sometimes getting better, sometimes worse.
I saw a lot of concern in the original github announcement regarding the use of the term "license." People felt it gave the team a legal footing to paywall features down the road and offer them only to licensed users, along with a few other concerns based in the legal implication of the term license. That of course runs counter to their statement that no features will be paywalled ever, so I guess there's still some anxiety over their trustworthiness out there. Understandable given some of the rug pulls that have happened in the open source world over the past year though (i.e Redhat, redis, etc...)
