E2E encryption only protects the data while it is in transmission.

If there is a breach, all of your data is accessible because it is decrypted at the endpoint.

Thats not what E2E encryption means. Encryption during transmission is called transport layer encryption (eg via TLS). E2E (end to end) encryption is encryption where the data is encrypted in transit and at rest. Generally E2E systems only have the keys to decrypt the data on the user's (endpoint) device.

Thanks for your comment. I truly had no idea.

This was very informative and changes my views on a few things.

That said, I'm pretty sure Zoom used your definition of E2E in their marketing so the confusion is warranted.
