This is badly written and ignorant article. Fat32 supports up to 16Tb partition size (depending on cluster size - 2Tb -16Tb).
Its microsoft’s windows tools that arbitrarily only allow users to create 32Gb partitions, and it is this that is being changed. This is not a change to Fat32, this is a change to windows. 3rd party tools on Windows and other systems like Linux have long offered more options for partition size.
That its taken to 2024 for Microsoft to fix the command line tool (and still not fix the GUI tools) is ridiculous.
