Change.org requires users to run nonfree software in order to sign anything.
I am always sad when I see that a petition I would like to support is hosted on change.org. That site requires visitors to run nonfree Javascript code in order to sign any petition. I won't publish a suggestion that people do this. I wish the site maintainers would fix that.
Alternatively, would someone who knows Javascript like to figure out how the site works and write a free script or Web-extensions front end for signing petitions on that site?
I wish I could sign a petition, but if it is on a site that requires nonfree Javascript code, I will neither sign it nor suggest that anyone else do so.
I urge people to call on the organization to change this, and in the mean time, not use the site.
