You can still buy a lot of titles at reasonable prices, but you also get situations were you can download the demo - offer to upgrade to the full version but it no longer exists in the store.
So Xbox Live is still supported but the store it is stuck in a partially preserved 2015 state, advertising Xbox One and a few upcoming titles. I have a series E 360 I bought last year dirt cheap as a way to get to a lot of titles no emulator currently supports. It is partially supported by Xbox One/Series X/S and if you want to get specific non supported titles to play, it is generally via rapidly aging, not very well built hardware. Xbox 360 as a whole is in a half dead state nowadays. I'm not a religious person but folks that produce emulators are doing gods work.
