Yes. Plenty of projects have gotten "in trouble" for copying code and illegally changing the license, either inadvertently or deliberately. The punishment is generally a complaint, and the remedy is that they fix the attribution. Examples:

- https://github.com/Lutando/Akkatecture/issues/19

- https://github.com/Grover-c13/PokeGOAPI-Java/issues/490

- https://github.com/dsiguide/dsiguide.github.io/issues/14

Such problems do not end up in court for two reasons.

First, it costs very little to bring a project into compliance with a permissive license — all you need to do is give attribution. It's not like GPL enforcement, where you have to choose whether to open source your proprietary code or to purge the GPL'd code from the project in order to achieve compliance.

Second, the culture of permissively licensed open source communities is such that they don't generally want to foster a litigious environment which would frighten business users.

If your point is that all they need to do is make the appropriate attribution, then we're in agreement.
