George Takei has indeed.

Unfortunately, I couldn't find any example of him talking about his time in internment camps on his mastodon instance, nor at his Comicsands site.

For years he has been speaking about this subject. He has Ted talks, lectures and podcasts.
I picked one example. I am sure there are better ones out there.
