When you include political messaging with your FOSS project, you make potential users have to consider if they want to "support" that messaging by using the product, you may get users of that project in legal trouble in some jurisdictions, and you may even attract state actor-level issues like what happened to Notepad++. I know it's mostly futile to ask, but consider just shipping your code without politics and leaving the political messaging for a personal blog or social network feed.
