Very large companies are definitely at the mercy of governments. Just look at how they are bending over backwards to comply with DMA etc. So, it is not at all inconceivable that they are forced to put backdoors into their product by the governments.
Thankfully! At least in a democracy, the government is chosen, megacorps are accountable to no one else.
