According to the person who cracked Modern Warfare 2 Remastered, the game doesn't have a proper always-online DRM scheme where it's storing data server-side and stuff lik ethat. Literally all it does is call home and throw an error if it can't get an appropriate response. Modern Warfare 2019 is the same. The difference is that MW2019 uses a more complex implementation of the Arxan anti-tamper technology which makes removing the checks much, much harder.
Why is MW2019's Arxan more complex? Partially because they're using Arxan to make cheating in its MP harder. MW2 Remastered is SP-only. Plus it's not as high profile a release.
Quite honestly, though, this is a situation where Activision have been screwing over SP Call of Duty fans. Not only are they forced to download HUGE patches for the MP when they just want to play the campaign, but when MW2019 came out, the game was unplayable for days due to the servers overloading. So you'd be unable to play a singleplayer game because the servers were crapping themselves. The rudimentary online checks for SP are only in the PC version, BTW. Consoles can play offline with no issues.
