I see, so it turns out you didn't care about the encryption, but do care about lying about something you don't care about. An interesting hill to die on!
Yes, that people should have correct information to base their decisions on seems like an important hill. Even if I personally didn't expect Zoom to be end-to-end encrypted, because I as a technical person know that's difficult for what they're offering (and didn't look at their marketing pages).
Are you actually surprised people don’t like being lied to? Zoom behaves like malware in a number of ways (just look at how the installer works!), and the company outright lies about features like this. Yes, people are going to be upset about this behavior.
I think it’s pretty normal to care about truth in advertising. Also, there have been many revelations in the past few years about internet surveillance. And to top it off, the EARN IT act that’s currently being considered in the US Congress is ultimately aiming to ban end-to-end encryption so passions about this topic are running extra hot. Put all that together with millions of people stuck at home being forced to use Zoom meetings, and you have the ingredients for a pretty good rage cocktail!
This seems really disingenuous, like you care more about dissing someone than understanding the pros and cons of using this tool that suddenly is one of the only ways to connect with people.
