> I'm a one man band who wants to be scalable, but doesn't want to get married to a particular cloud.

Just pick a cloud provider and move on. All of the top-tier providers can scale. Choose the one you're most comfortable with and move on. Focus on the things that matter for your business like building the right product and getting customers. If you have regret later, it's going to be because you were so wildly successful that it is now an actual business risk and/or your customers demand it. But don't make this decision based on a problem you don't have and are unlikely to have in the next 12-24 months, if ever. Cloud agnosticism is rarely a functional or strategic requirement of any given business, and it's usually very expensive to implement--more than any savings you might achieve by pitting providers against each other (which you can't do anyway unless you are big enough to be a strategic customer).
I'm writing a public statement platform, and a core design priority is to avoid being Parlered, since human moderation is not an option. Responding to court orders is inevitable, but responding to cloud provider demands isn't quite, yet.
The thing is that avoiding cloud vendor “lock-in” won’t necessarily help you here. If it isn’t cloud provider demands it’ll be someone else involved in serving your content, could go all the way down to your ISP.
