Interesting - you are concerned about a threat but you have not taken
any steps to see if that threat is valid in ordinary Qubes use.
You could, of course, actually read the Whonix wiki on the subject, and
follow up on the material suggested for Kloak.
There are large corpora of mouse and keyboard data available. I have
used those with custom ML to see what effect using VNC and separate
qubes has on data acquisition. You could do the same.
You are wrong, but it would be worth while testing this further…
I can only report on estimates made from surveys. If you read in to the
field yourself you would see that there are very few surveys of (eg) VI
computer users, and informed estimates are all we have. An interesting
statistic is that take up of assistive technology like screen readers, is
relatively high among non impaired users.
I see that other users have commented on this. I am somewhat more resigned
at such comments than they are. I would say that it’s an area where you
might like to inform yourself further.
There are many impairments that make mouse or trackpad use difficult:
beside VI, many motor difficulties make accurate mouse use difficult,
but a simple keyboard overlay can help. Users who rely on pointers or
wands, users with RSI - I’m sure you can think of more yourself.
Many of these people will use a normal keyboard and a “normal” browser.
Some will use a screen reader. Relatively few will use text based
browsers.
If you read only one article on computer use by VI I recommend
this outline by Karl Dahlke
I never presume to speak for the Qubes team.
When I comment in the Forum I speak for myself.
