It's why I've avoided anything smarthome tied to any particular vendor.
My endpoint devices are almost entirely Zwave or Zigbee/Matter based. I started out with a SmartThings hub but migrated it all to Home Assistant last year. HA has honestly had easier integrations than SmartThings did and supports almost anything under the sun.
I don't have to worry about suddenly losing control of my devices and the only 'subscription' associated with it all is $15/year for a domain name to make setting up remote access easier. This approach requires a little more research, but it opens up the ability to mix and match devices however you'd like. Absolutely zero regrets.
