Arm Acquires Minority Stake in Raspberry Pi

This is a most excellent place for technology news and articles.
At the moment their current OS is backwards compatible with the 32-bit Model B+ they released back around 2014, so only one distro to maintain and one set of kernel modules etc. I can imagine they probably have a very close relationship with Broadcom at this point too...
It's slightly disappointing, but it's still very, very early days for RISC-V, some things just aren't there yet like the value for money, performance per watt, and support for various hardware features. In a few years though things will look very different...
AFAIK Broadcom/Broadcom employees is/are who founded the RaspberryPi Foundation for educational purposes.
Edit: after a bit of googling this isn't accurate but Broadcom does supply funding and has some employees on the board so it seems they play a big role in the organization.
Rpi is basically just a broadcom promotional tool that got out of hand.
