Not necessarily, if they can produce the crops more cheaply. Since each country ideally wants to secure it's own food supply, it's inevitable that many countries will find themselves subsidizing local production that would otherwise disappear in a competitive international market.
Additionally, hostile countries do not need to flood markets sustainably if the goal is simply to hollow out food production in the target country before taking more overtly hostile (i.e. military) actions.
That's partly the point though, isn't it? You're not accountable for your performance, you're accountable for the performance of the company. And the performance of the company could be extremely good or extremely bad, very much independently of your contributions.
are these actually lies?
i know tesla stopped accepting bitcoin but it doesn't seem surprising to operate nodes when they did accept it. companies change policies all the time so i wouldn't call this a lie unless they never did it all. is that public information?
"almost all" possessions is pretty vague. perhaps this is false but it's not obvious at face value and wouldn't be malicious. it seems mostly a question of semantics (does renting = owning? do we mean houses and cars or clothes and silverware?). if someone tweets "i'm selling all my shit" are they lying?
break pads never needing to be replaced is obviously not 100% true since some percentage of every part will inevitably break, but if pads without defects outlive the rest of the car, i don't see how you could disagree with this statement. teslas are barely old enough to evaluate this statement and doubly so for cars produced in 2018.
i don't follow this stuff nearly closely enough to know if these are lies and it's not clear to me the information needed to evaluate those tweets is publicly available or even exists. i don't dispute he's made misleading statements and exaggerated but i'm not convinced it's obvious he's lying or that not seeing it means you have blinders on.
