Maybe try google before making statements like that. The decision was Bernstein vs. US.

Prior to that, export controls prevented PGP source code from being exported from the US. Advocates printed it in books and exported those, which helped clarify the issue.

Bernstein was a math student who made his own encryption software. The government tried to make him register as an arms dealer, and he sued in 1996, with the backing of the EFF. The result was a landmark decision that established source code as free speech and basically destroyed export controls on cryptography.

In 2016, Apple cited the decision when the government tried to hack a suspect's phone, saying they couldn't be compelled to "speak" by writing code.

Correct. This is so wildly misunderstood. Zimmermann was investigated for 3 years but formal charges were never filed.
