I've always needed to buy first-party batteries to replace worn out ones, and if I'm doing that it doesn't make any difference to me if their interface is proprietary or standard.
Sell me batteries worth a damn, then we can talk about standards.

Once you have two battery types, you might as well have a few. People seem to be quite fine with M12 and M18, which are only compatible on the charger itself.
It is much less important to have access to multiple brands now compared to 20 years ago, as most of the brands have acceptable tools across the line even if they're not all the "best in class".
But that doesn’t matter! If, say, Makita, Bosch and Hilti started using standard, interchangeable batteries, you could use Makita, Bosch, or Hilti batteries in tools by any of the three brands. No need for third party batteries.
