The author, a new Sony shooter, discuses the obvious cynicism of the 'sensors are us' company here. He surmises
Sometimes, it feels that Sony is a giant corporation that makes sensors and that its cameras are almost a byproduct. If it can undermine other camera manufacturers by releasing a product {like the A7R IV} that blows theirs out of the water (while overlooking so many other aspects), then why not? Four years on, it’s still not clear whether Canon will be able to match the performance of the sensor in the a9. Imagine what the a9 II might be about to offer.
