I went into this issue when I did a youtube segment on security of Zoom.
The problem with 'end to end' encryption is that it isn't the same as end
to end security and the developers may have a different definition of what
an 'end' is.
Have spent way too long explaining to folk that no, their data center is
not an end as far as end to end security is concerned.
I don't see why folk are beating up Zoom and blithely using dropbox and
slack. Well I do, but...
If you want end to end you need to do the whole job. Not just point
solutions. But right now, anyone proposing anything of that sort is called
