Chinese steel?
Look how much petroleum was wasted building ALL of those monstrosities…
IMH (mech eng) opinion, they underestimated the wind and resulting bending moment where the base of the wind turbine entered the ground.
If you have not seen “engineering disasters” about the Seattle Tacoma narrows bridge, there a videos here showing it flop around like a noodle and fall because the engineers miscalculated or neglected wind loads.

for example instead of ordering a specified grade of structural steel called out they could use some common pipe material thinking the engineers callout for the expensive stuff is "overkill" and send out their rookie welder to glue it up because there is no "public safety " to worry about out there in the field anyway
NO.
Simple physics.
Essentially those wind turbine propellers create centrifugal force. Anything that “cycles” creates this force from wind turbines to basic electricity.
Ever have a thing as tiny and simple as a light bulb, suddenly flickering on/off and is loose in the socket? OR you go to remove a burnt out light bulb you know you never put in that tight?
Yes, wind is energy. And contrary to what the environmentalists want you to think, there is a payment due for using it beyond natural resources.
The payment comes in the form of basic 101 Physics. Enough force will loosen the windmill from it’s base. And that force will come as too high of winds or too long of winds.
