If the right exists, tools can be built to exploit it. For example, one could write a tool that ingests Google Takeout data to convert it for other platforms, because the data output exists in a... somewhat... usable form. Presumably, someone wanting to build a service that encourages people to migrate from Google services could build an import tool to their platform with it.
