I'm eternally grateful to Google for HTTP/2, Chrome, Web Vitals, Angular and so many other puzzle pieces without which the whole Internet wouldn't be what it is today. It showed foresight, wisdom, excellence, responsibility and stewardship.
The problem starts where growth ends, and all growth needs to end somewhere. There are only so many people on the planet with 24h a day to spend.
When that problem starts, a corporation still has to maximize shareholder value, and that's where the formally great stewardship gets endangered.
And then Google used its web browser, standards and search monopoly in order to
- shove the open-but-really-not-open AMP "standard" down everybody's throat
- eat up any kinds of comparison competitors by stealing their content into the featured snippets
- ...
So going back to your question, I'd still mostly trust in the benevolence of AWS — but I have zero doubts this benevolence will go away as soon as there is an opportunity to crush a competitor by ignoring that benevolence.
To quote Jeff Bezos here: "Your margin is my opportunity".
