So here’s my $0.02 from the outside looking in since I’ve only ever had a V2 or V3 hub.
First, no migration utility does suck. It was promised forever ago for V1 to V2, never happened and now the top-secret one that sometimes can be used is for V2 to V3 only. So it’s gonna suck for the users that do choose to stay with SmartThings that they have to start from scratch. And i’m sure there will be plenty of people that would stay with SmartThings if there was a migration utility that will now leave to Hubitat or something else since they are starting from scratch anyway.
Beyond the migration, Samsung seems to be handling this rather well for V1 users. The V1 hub is 7+ years old which is an eternity in IoT. It was also developed pre-Samsung. So kudos to them offering a discount code at all for the new hub. $35 for a new hub is cheap.
For the Link and ADT hub, I’m kinda mixed. Both are ~3 years old since their debuts, but have been sold up until around 2 years ago I believe. The refund for the hardware and discount code on new hub is nice, but now that Samsung is going all in on WASH it doesn’t instill a lot of confidence in the longevity of a WASH hub.
