It’s complicated.

It’s not a constitutional right.

However, there’s a lot of case law that supports the rights of citizens to express their thoughts about governments. All levels all processes, with the exception of sedition, treason, national security, et cetera.

We do have strong defamation laws. There was a case a few years ago where a politician was found to have been “defamed” by another politician with respect to comments that were made.

We also have recently strengthened hate speech laws, which is the issue in this specific picture.

Finally spreading information that might compromise national security, and publications showing violence or other offensive content.

In practice, I expect that the situation is similar to what it was in pre-Trump America. However, it’s true that in theory the government could pass a law saying you’re not allowed to say anything bad about the government.

10 years ago any self respecting American would have pointed out how inferior our system is and that we don’t have any rights or freedoms. I feel like that imbalance has shifted however.
