I haven't kept up with Edge Shenanigans since I no longer use Windows, but the last time I used it I had no issues using Firefox instead of Edge.

Yeah sure you can add repositories to replace Canonical Sources to evade those dummied out packages, but you really really shouldn't need to do that in the first place.

So the only difference is: MS enforcement is more stringent than Canonical, but they both force their respective ways onto the user (which may or may not versed enough to actually add/remove apt repositories).
