This PR release says the point was "Developing the Most Broadly Used Enterprise End-to-End Encryption Offering" (https://investors.zoom.us/news-releases/news-release-details...)

Five months later, they announce their initial technical preview of E2E encryption (https://blog.zoom.us/zoom-rolling-out-end-to-end-encryption-...)

What usually happens after M&A is if the acquired product isn't a profit-maker, they "integrate" it into other products and it goes into maintenance mode, eventually to be sunset. If the product did make money, they'd re-brand it and keep development going... unless they have plans to integrate the product's core feature into a larger corporate product (Zoom) that a separate branded product would compete against internally.

It seems like keybase has been eaten and absorbed into the Zoom app, and the rest will be flushed.
