I'd be careful with swift generalisations. It depends a lot on the value of your product. I didn't have any hangups about installing a plugin to use my TREZOR: compared to the cost and effort involved with the rest of it, installing a plugin was by far the easiest part.
Another example. Back in 2005 people also used to say that nobody wanted to download apps anymore. Then I started working on Google Earth, which got ~400 million installs. Obviously, that was cool enough that people were willing to download and install a giant hulking ugly Qt app :)
