Elon Musk Controversial Salute Image Beamed on Tesla Factory in Berlin

The large image shows Musk giving the salute with the words "Heil Tesla" beamed above him.

@andrewstroehlein i went into the article totally prepared to believe that elon had actually organised it to happen himself, as part of some weird edgelord troll marketing effort. We live in very confusing times.

@andrewstroehlein
It seems to be a photomontage but so near to reality that everyone would buy it.

Edit: or maybe not, the activists today insisted it happened; also noted in the article.

Zentrum für politische Schönheit: Aktivisten posten Bild von „Heil“-Projektion auf Tesla-Werk

„Heil Tesla“: Die Aktivisten vom Zentrum für politische Schönheit und von der Gruppe „Led by Donkeys“ haben in den sozialen Netzwerken Bilder von Projektionen auf dem Tesla-Werk in Grünheide gepostet.

@andrewstroehlein I hope they are run out of the country.
@T2R @andrewstroehlein
Sorry, you need to clean up after yourselves. We already have enough of our own trash.
@andrewstroehlein People worldwide have got to keep spreading this around and not let it get covered up or brushed over.
@andrewstroehlein "Heil Tesla"? Warum, ist sie krank?
