Monsanto very infamously sponsored studies all over the world and with prestigious universities and professors that "found solid proof" that GMO's plus RoundUp was "non-toxic", but now we know that RoundUp in large quantities clearly causes cancer.
It's too bad because now, I am honestly can't tell if any study on GMO's is valid or sponsored by these large corporations.
I don’t think we do know that. Unless Wikipedia editors and European regulatory agencies are Monsanto shills. https://en.m.wikipedia.org/wiki/Glyphosate
If you saw how far Monsanto's reach was, you would know that Wikipedia is child's play. And they infiltrated other governments, so the European regulatory agencies are clearly within their wheelhouse.
Here is one example of when they corrupted a Harvard professor.

He doesn't have to lift a finger and gets credit for a study plus thousands of dollars.
Corruption at it's most efficient.
