> they clearly added value
A tiny amount compared to the whole, Core Devices' own contributions are larger, and the firmware remains open source! Nothing was stolen!
As for Eric giving credit to Rebble:
repebble.com: "This was also made possible by the Rebble team and community, who have supported Pebble since it shut down"
Eric's YouTube: "thanks to the clever work of Liam, one of my past Pebble colleagues and avid Rebble contributor, we switched to using an open source BLE stack called Nimble."
Eric's blog: "thanks to Rebble for keeping everyone engaged with a product that hasn’t been on sale since 2016!"
More on Eric's blog: "For the last 9 years, the Rebble Alliance has been keeping the Pebble dream alive. [...] I’m a huge fan" "Without the community or the OS, there is zero chance that these new watches would be possible! Thank you Rebble!"
Yet more on Eric's blog: "I’d like to thank [...] The Rebble Alliance - they’ve been keeping the Pebble torch lit in the intervening years, and (hopefully) continue nurturing and empowering the community years into the future."
Eric's social media: "Thank you, Google and Rebble! I can't stress how thankful I am to @pebble_dev (http://Rebble.io) and Google, in general and to a few Googlers specifically, for putting in tremendous effort over the last year to make this happen. You've helped keep the dream alive by making it possible for anyone to use, fork and improve PebbleOS. The Rebble team has also done a ton of work over the years to continue supporting Pebble software, appstore and community. Thank you!"
