When FitBit bought Pebble in 2016, some may argue that this was a good thing, the development of the watch and the OS just stopped - it was dead. FitBit had no intention of keeping the Pebble and just wanted to implement the software into it's own ecosystem.
Google bought FitBit in 2019 and released the source code for PebbleOS this year - but that is kind of late now, isn't it?
