There is an important technical reason why I say no JavaScript on Web pages
should be executed, even if it's libre. My essay explains that reason:

This can be overridden by a very drastic overhaul in how a libre browser
handles JavaScript, but it would be such tremendous work that I doubt anyone
is going to be able to step up to it. LibreJS is not a solution, nor even a
step in the right direction.
