The Spanish government is not the ones enforcing the ban here. La Liga and Telefonica went to the judges, who are the ones making ISPs to enforce these blocks, as an intermediate "fix" essentially.
This appears to be using "government" in American English sense, where "government" refers to anyone who works for the state in any capacity, including courts, not just the executive.

Which are part of the Spanish government.
Do you have an English word you can recommend that refers to what (in American English) I call the entire government of a nation?
