The takeaway seems to be "you must pay for every query and for every bit and byte we hold and transact for you", here's a list of companies you probably never heard of before (Upstash, Momento, Stellate, Xata), some with unsearchable names (Convex, Temporal, Trigger), pay them to have your database locked arbitrarily or whenever they somehow reach unicorn status and will be too big to reply to your emails.

Accessing the website of any of the listed companies, the Pricing page in the header is predictably there: everyone is looking for a rent. Just to be a contrarian, because I just can't believe all these companies are making significant money, perhaps it's time for a return to the pay-for-binary model in such an Everything as a (payable) Service world: here's the blob for a nice database (or whatever), pay $1,000 (or maybe even $10,000, $100,000) and the current version is yours forever.
