I guess what surprises me here is how much of this is 3p code that couldn't possibly be distributed. Like why would you not be using an open source web server, or widely available message broker? Things like chat moderation/match making/anti cheat/etc seem like add on services that would be implemented per game (well, maybe not match making) and aren't relevant to the problem that the "stop killing games" people are trying to solve.
Frankly it's none of your business why, and it's completely irrelevant. The fact is that this 3p code exists and this law needs to account for it or it's unworkable.
