As a general rule, if you buy “smart” anything where it requires an internet connection and a cloud service to function it will be bitrotten within 5 years and dead within 10. And that’s assuming the company survives so long and is bothered to support it. That’s from planned obsolescence and the ongoing cost of supporting the platform when they have something new to sell. And while things can benefit from an internet connection, if its white goods then run a mile.

I think forward thinking companies could actually gain a lot of free publicity and sales if they openly pledged that their software was in escrow and would automatically release after a period of time and/or as a failsafe if the company discontinued the product and/or they went bust.
