I don’t see this as enshittification. It’s a real thing that’s happening, but raw storage is expensive. They pay for it directly. Unlike artificially limiting features that are “free” to them, this genuinely isn’t, it’s not even really super discounted for them on the backend. They’re likely just paying for a series of S3 buckets.
I’ll believe it when I see it. Apple has a demonstrated track record of supporting their phones for years, Google has a demonstrated track record of killing anything that isn’t an immediate run-away success. So sorry Google, but I can’t just take your word for it.
