People's saltiness about the consumer/advertising side of Google having killed their favorite free product is pretty irrelevant in this context.
> same people are making decisions in upper management.
That's not true. Google Cloud has its own CEO and a very different business model.
> they don’t make anything if it is not bringing more revenue.
Sure - they're a for-profit business. Google Cloud's revenue was $13bn in 2020, and as of last quarter it had a run rate of $22 bn. That money comes direct from paying customers. The business model of the consumer/ad side really is irrelevant here.
Business model is different indeed, but the parent company is still Alphabet, which in the end has huge influence.
I understand not all large companies have the luxury of picking their service providers but I do believe it's in everyone's best interest to diversify web service infrastructure. One, to hedge against catastrophic failures that may arise from their platform going down and two, to better balance the distribution of power on the internet as a whole.
