The potential for reprisal in expressing your choice or opinion in some circumstances is very high and anonymity is sometimes the only thing that can eliminate the chill of that risk. It is in this way a free speech issue.
On the other hand, if a crime or tort was committed, well that isn't considered free.
Interestingly, this has not always been the case. Elections in the US did not use anonymous voting until nearly the 20th century. And the reason for instituting the secret ballot was apparently less due to free speech concerns, and more because of rampant corruption and bribery to buy votes.

And this is a tort case
British elections aren’t anonymous - the ballot paper has a unique identifier and this is written beside the voter’s name on the polling station’s list when the ballot is issued by a polling clerk.
The list is sealed when the polling station closes, but can be opened by court order if the election result is challenged.
Ballot papers (votes) and their corresponding number lists (matching voter to ballot paper) are kept for 12 months before destruction, and together allow who voted for who to be known - however - it seems no-one is allowed to inspect this except for the purposes of prosecuting an electoral fraud, so votes are to all intents and purposes private.
Perhaps the top downvote was for pedantry (?), but there is a difference between anonymous and private. The British system could issue ballots without recording to which specific person - that would be anonymous. You’d lose the ability to ask a particular voter if their counted ballot was the one they marked (substitution fraud), but I don’t think this ever actually happens.
I didn't know larping was illegal
1) The Twitter user isn't charged with anything, so no one is trying to restrict their speech.
2) Anonymous speech isn't the same as free speech
3) This is a civil suit. Civil suits have always been able to compel the disclosure of some private information in some circumstances.
