> I suspect there was an internal deck saying how this acquisition is going to give them foothold in the hobby community,

No. This is to give them a foothold in the "IoT hammer" manufacturing business. They looked at how the Raspberry Pi went from cheap hobby computer running Linux to low effort rapid prototyping embedded platform that can run a full web stack. They want to be part of a full dev pipeline from prototype to product.

The real target audience are people building things who don't care how it works as long as it works. So expect 99.9% of these projects to use some sort of Python or JS thing running in a container on the Linux while the microcontroller runs a few lines of c to manipulate IO pin state from the Linux thing. Just like all those abandoned Spin scooters in Seattle that had raspberry Pi's in them. That is the market they are after, not the person who builds a one-off Arduino fish feeder.
