AFAIK the protest surrounding the tesla factory were more related to the horrendous work culture that is present at tesla and the amount of pollution that has reportedly been found dumped by tesla factories. 'Because reasons' seem to imply that allowing a tesla plant to be constructed in your country is a resounding net-positive for that country but I think Germany was correct in assessing that the "tesla mindset" isn't completely in line with (West-)European ideals.
