There is one megafactory: https://www.tesla.com/en_eu/megafactory

I thought gigafactory had no meaning other than Tesla's marketing speak for a large factory, but apparently the term is gaining traction for better or worse:

> The term "gigafactory" has also been adopted by other companies which are involved in the manufacture of electric vehicles and other clean tech products. Established automobile manufacturers such as Jaguar and Volkswagen now use the term to refer to their own electric vehicle factories.[6][7] Newer companies such as Stellantis have also embraced the term[8] by referring to four new "gigafactories" in France which will produce lithium-ion batteries for electric vehicles. Other companies such as Holosolis[9] and 3Sun,[10] which only produce solar cells and finished solar panel assemblies, also use the term "gigafactory" to refer to their facilities. The term is therefore understood to generically refer to large industrial facilities which are associated with the decarbonization and electrification trend.

I just don't think this is a practical argument. You have zero control, influence, or access to the businesses BlackRock controls. By contrast Larry Fink has the power, which he has regularly exploited, to reshape entire economies at the snap of his fingers, let alone just one of the many businesses under their control.

Where's the line? Does Berkshire own Apple or is it just Berkshire's shareholders who do? Does Google own YouTube?
