If I were in your shoes, I would probably mention the change in tone/word choice to the lead on the project since you have a good relationship with them. Just mentioning that you noticed the change and aren’t sure about it doesn’t need to be combative, and I would be truly shocked if it cost you the job. Depending on your state it might even be illegal to fire you for something like that.

I personally would not take a stand or refuse to do the voiceover or anything like that. I would make it clear that I would do the voiceover using the script as it is written. I would think of it as providing feedback rather than making demands, which seems like it would be within the purview of a QA reviewer.

This way you can at the very least get more information about the situation - find out whether this was an intentional change. If so, it may be time to start making moves so you can eventually drop this company.

Very cool. I wonder how durable these electrodes are once coated in nanowires.

As I understand it: The long term vision is that by increasing the cost of imported goods, domestic goods will have an easier time being competitive. The short term vision is that tariffs can be used to bully other countries into doing things the U.S. wants.
