Impersonal collection and personal collection evokes very different concerns in people. Impersonal bulk collection is easier to dismiss as "they're not looking for me", whereas the latter raises all kinds of questions about motivation.
That argument is a bit vague. How does minding work in this case? People who are opposed to CCTV will try to avoid it. But will that avoidance be visible to the rest of the public? Hardly so. Besides, many cameras tend to be placed at places where cameras blend in and you need to make an effort to actually spot them.
We can also expect a company like Apple would be very risk averse in this regard, and keep far away from anything too weird.
Some random guy doing their own project going by just whatever seems reasonable to them and installing surveillance software on somebody else's computers isn't really the same sort of thing.
Surveillance Camera Man showed that people have often violent reactions to being overtly filmed by individuals in public. These videos appear to be gone from Youtube now, but if you hadn't seen it he would often just film people do mundane stuff in public like drinking coffee. People always questioned what he was doing, he would tell them "I'm just making a video" and they wouldn't be pleased.
If you told someone you were going to install a keylogger on their machine they would almost certainly be against you doing that. But people voluntarily use "cloud" services like Google Docs etc. which are literally keylogging devices.
I think there is a strong tendency for people to submit to what they consider to be authority. Some random guy on the street isn't authority. But the government is. Apple, Google, Microsoft etc. are. Unfortunately it leads people to spend energy on things that don't matter, like the random guy on the street, and not the things that do matter, like systematic global surveillance.
