I don’t consider this vendor lock in; more other-vendor lock out. Which is not to say it is necessarily better or worse - it’s just different.
For a company with internal IT or IT capable people, that’s a small hurdle if running the software is not too hard.
For a company with all IT outsourced, this is a deal breaker.
It will likely stop the behemoths (AWS, GC, Azure) from capitalizing on that product though.
