I don't know but for the past 2-3 years Google has been on some crusade to reduce its storage usage/customers. For me it started in 2020 when Google announced my Firebase storage usage would go from maybe $20 per year to something like $800 per year, for a single app. Apparently they had forgotten to charge Firebase users for egress, for years. But then also Gmail stopped adding more storage at some point so I was forced to get a Google One subscription or migrate 15 years of emails to some other service. Etc. I suspect Google has realized it's better to reduce its storage customers and just keep the ones that are ready to pay more, instead of expanding their storage capabilities ad infinitum.
