Actually it makes perfect sense for all the reasons you stated.
"Funded businesses die all the time. Google cancels products all the time. companies are acquihired and products end of lifed."
So it makes perfect sense to avoid Google offerings (especially consumer side ones, which Google kills whenever it wants) and avoid "funded businesses" and newcomers that in danger of being acquihired and EOLifed.
Letting the careless early adopt those kinds of services, and using only mature ones (that have proven their longevity and aren't going anywhere even if acquired) in your company, makes sense.
