The list of locations with those laws is growing very large. From the post:

> Last summer we announced a series of changes to the terms and conditions of the Matrix.org homeserver instance, to ensure UK-based users are handled in alignment with the UK’s Online Safety Act (OSA). Since then Australia, New Zealand and the EU have introduced similar legislation, with movement in the US and Canada too.

...and while we have no choice but implement it on the matrix.org instance, other folks running their own servers are responsible for their own choices.
