I read in some of the news that this was an overinterpretation of the sanctions by the companies, but I don't know if it's really like what happened to other transnationals that have withdrawn from the country due to the losses and restrictions of repatriating their capitals to their parent companies.
If this were the case, it would not make sense to make an excuse, but that may be more appropriate than accepting responsibility for their actions before public opinion.
If in fact they did it for a correct interpretation of the sanctions issued, because the effect can be problematic, as it could mark the beginning of a massive withdrawal of international companies that are still in Venezuela.
I think that the case of transnationals is due to other reasons.
These two companies that I named are the first to state that they took these measures motivated to sanctions. In any case they are not apologizing, but notifying their customers to take the necessary precautions.
