>gives users plenty of opportunity to move, they won't suddenly find themselves without a provider.

in some sense what i describe is worse than just sudden (i.e. a 1 year like notice which is pretty sudden in the enterprise time scales) death of a provider as the customers will be "slowly boiled like that frog" not feeling urgency to move at any given time while the platform will be falling behind and into more neglect.

>concern about the provider's future

it is concerns about provider's ability and, most important, willingness to support (i.e. to invest in) the state-of-the-art of the platform in the years to come. There is no such doubts about AWS nor Azure. It is too unfortunate for GCP that ARM popped these couple of years - Google has to decide right now and that is already pretty late whether they are going to invest a bunch of billions in having [competitive] ARM in the GCP. It is not just a matter of getting an ARM license and printing the chips, it is whole stack optimization to get those "40% faster at 20% cheaper" (as claimed by AMZN and with such improvements even native platforms of large slow BigCo-s like ours will probably move to support ARM while x86 will become more like PowerPC "supported too"). I think the Google management wouldn't risk venturing into ARM, at least not to the scale needed.
