I'd like to think that this could be a positive thing; but with everything I've come to understand about their way of doing things makes me very much doubt this.

Amazon, by having 'competitor's shops' within their own shop for a number of years now, has used the telemetry to see how their competitors earn money and have used this data to undercut them. It might be a dollar here or a dollar there - but ultimately they'll have a monopoly.

The point that you make that they're reliable is true - but also that they've reliably misused their power - whether it's the example above, or how they treat their employees.

Just as Elon Musk decided to pull the plug on Starlink services for the Ukraine at a crucial moment when he wanted to - what's to stop AWS doing the same when there's voting for a hard fork?

You can't 'vote' when there's a potential hard fork if you no longer have a node.

Just my two sats.
