The first one was about an advertisement pixel, which everybody is doing but for some reason surfaced only for Zoom.
The second one is end-to-end encryption, which is not expected at all for VC apps. NOBODY does it!
Irrelevant. That as nothing to due with the fact that they say they are. Zoom is being completely dishonest, and as some other commented here, some orgs like in health care area, have E2E encryption as requirement, Zoom says they have, but don't. It's literally fraud.
"Achieve HIPAA (signed BAA) and PIPEDA/PHIPA compliance with complete end-to-end 256-bit AES encryption."
2. end-to-end has several meanings, for users it means what Signal does, for machines it means TLS is securing edges.
According to the article Apple does end-to-end encryption for video conferences. Also other providers are not lying about it like zoom does.
Google Duo does.
